60=. Caitlin Moran, Journalist
Moran is an example of a writer who has used the medium to introduce herself to readers away from her main platform – in her case the paywalled borders of The Times. It's probably no coincidence that, with almost 200,000 keen followers, her latest book, How To Be A Woman was such a huge success. Moran is a witty 140-word commentator on anything from workfare to St Etienne album covers and an endless contributor to a flow of rude banter with fellow writers like Grace Dent and Alexis Petridis.

60=. Mehdi Hasan, Journalist
The New Statesman's senior editor is a frequent voice on issues in Westminster and beyond. His feed is full of retweets to key articles, links to his own pieces, debates with other hacks and snippets of opinion – making his feed a hive of curation and interactivity, just what the medium is built for.

62=. Neal Mann, Journalist
A "Twitter anchor", Mann has been breaking news seconds ahead of conventional websites since 2009, with his huge network of followers as sources and amplifiers. The Twitterverse demands constant attention in the search for the next scoop; his feed curates tweets and links from news sources all over the world and is the first place to hear who's died, apologised or lied. He's not above a bit of light-hearted comment, though: "It has finally got serious – Sean Penn wades in to the Falklands row." (February 2012).

62=. Laura Kuenssberg, Journalist
The ITV News business editor is firmly finance-focused, generally broadcasting breaking news and giving an inside view on the interviews and conferences behind the headlines. From a meeting with Barclays' boss Bob Diamond, she tweeted: "Attempt number 2 to get Diamond to talk about his bonus, again, 'this is about the results, but thank you for the question'." She also asks followers for questions while keeping up a steady stream of informed business news for the savvy follower.

62=. Phil McNulty, Sports journalist
As the chief football writer for the BBC Sport website, McNulty has a large audience, with every one of his frequent blog posts picked over by adherents and critics alike. His Twitter feed consists of links to the blog, live match commentary and healthy football-based debates with his followers. He frequently squeezes considered analysis into 140 characters, to wit: "Wenger has earned the right to try and turn Arsenal around – but there must never be another last day transfer trolley dash."

65=. Rory Cellan-Jones, Technology journalist
The former business correspondent may have come late to the technology party (he was not, he claims on his blog, the owner of a Sinclair C5 nor did he build his home computer) but he is now one of its biggest champions, having covered everything from the 1990s dotcom bubble to the rise of Facebook and Google. Tweets are matey, but informative. "Just tried to join hot new social network @pinterest and found there's a waiting list. Is this just a smart way of making it seem exclusive?"

65=. Alastair Campbell, Former spin doctor/diarist
The former Downing Street director of communications hasn't lost his appetite for putting his own spin on current affairs. He just does it through Twitter these days, instead of through national newspapers.
Following his Sky News tête-à-tête with Adam Boulton in 2010, Campbell managed the message almost as soon as he went off-air: "Really worried about Adam Boulton. Wonder if he might need some of my pills." There's rarely a big political story that Campbell doesn't tweet his take on, usually with a brutal directness. He's also keen to reflect and share ideas about mental health and his beloved Burnley FC (hence the "claret" in his user name).

67=. Lucy Marcus, Businesswoman
The founder and head of Marcus Venture Consulting, Marcus is also a columnist for both Reuters and Harvard Business Review and is a major voice on boards and corporate governance. She tweets breaking financial news as well as her own views on big issues. It's a seriously impressive source for information on a range of business topics – from "Has mobile money's moment come?" or "Which tech cos [companies] come out tops in fighting climate change" to the scandals about child cotton workers. Useful reading for business experts and neophytes alike.

67=. George Monbiot, Academic and journalist
The self-styled "professional trouble-maker" is as feisty on Twitter as he is in his Guardian columns. Monbiot isn't afraid to use Twitter to call out anyone from mining corporations to climate deniers and politicians: "No bloody way: Cameron says he is committed to abolishing the top rate of tax. Insane and injust."

69=. Bill Bailey, Comedian
The "keeper of the eternal flame, occasional bouzouki player" (that's his Twitter profile: a bouzouki is a sort of Greek lute) updates his followers on life on the road, frequently posting arty photos in a "Touring views" series (a view from Tebay Services was genuinely captivating). He does not, however, share news of his lunches; a banal, fictional exchange about a sandwich was the subject of his Emoticon Twitter song, which can be found on YouTube ("You tweet, OMG I'm having a sandwich, like it's thrilling... Four seconds later 19 followers tweet, 'what filling?'")

69=. Jon Snow, TV news anchor
Snow's reputation as a likeable, but no-nonsense newsreader translates easily to Twitter, where he's been a strong presence for a couple of years. Likes to drop in pieces of trivia around breaking news ("Last shedding of a knighthood: Anthony Blunt..." he wrote after Fred Goodwin's was shredded), but principally provides regular updates of what's on Channel 4 News and in his blog. Hints of interactivity ("I am debating rail fare rises tonight with industry and passenger groups on C4 News. Tweet me questions...ta, Jon") add to the appeal.

69=. Owen Jones, Writer
Owen Jones's first book, Chavs: The Demonization of the Working Class, established him as a very young version of an old-school social campaigner. His tweets range from full-on political invective: "Soaring unemployment, growth sucked out of economy, borrowing targets exceeded, credit rating cut. On every measure Tory policies a disaster", to humble self-mockery about his appearances on prestigious national news programmes: "Will Twitter's servers explode with all the 'Isn't it past Owen Jones's bedtime' tweets? Guess we'll find out with tonight's #bbcqt."

69=. Susanna Lau, Fashion blogger
The self-made queen of independent UK fashion blogging pumps out content on seemingly every show and event in London, from her own TV appearances to the Occupy Fashion Week protest. It's a great gallery of style links and pictures of clothes and beautiful places, plus connections to more of the same at the StyleBubble blog. Everything you'd ever wanted to know about, for example, the "really simplified take on the leather harness" or Anna Wintour's hair colour (February 2012).

Co-founder of Tweetminster, an aggregation site that uses data to select the stories being read by the movers and shakers in British politics. Nardelli's feed, incidentally, does much of the same – swiftly jumping between politics, economics and politics with dozens of links to the day's stories, from fraud in the eurozone to youth unemployment in the UK. His following is small but highly influential.

The author and Sunday Times columnist is a Twitter stalwart, friends with Caitlin Moran and just about everyone else. She's an avid experimenter with all kinds of social media, recently announcing: "It's exhausting. I'm doing Twitter, Instagram (my fave) and now this and culling everything else." (February 2012). Well, you wouldn't want to take it too far, would you? Topics vary from political campaigns to the very personal. On a trip to a private clinic with a family member, she wrote: "You slightly suspect half the women are here to have their vaginas tightened." (February 2012). Wow.

A frequent contributor to newspapers and magazines such as New Scientist and Nature, as well as a one-time employee of the Royal Society of Chemistry, Bradley is the man behind the Science Base blog, and one of the more approachable science voices on the web. He makes full use of the @ button to interact with fellow scientists and enthusiasts, and posts links not only to his own blog, but to interesting science-related stuff from elsewhere, too.

Whether in a select committee, the Commons or online, Mensch is a wonderfully combative MP. She's used her feed to call out colleagues and journalists, hitting back against those who criticised her for appearing in a GQ photoshoot and even using a Blackadder line to answer suggestions of a facelift: "A man's soft lips are his own private business, sir!" The novelist-turned Tory MP also proved her mettle when she handed over details of an online abuser to police: "I don't bully easily, kids. Or in fact at all," she wrote at the time.

77=. Alan Rusbridger, Newspaper editor
The Guardian's editor uses his account mainly (and unsurprisingly) to pick out stories from his own paper – especially breaking news and coverage relating to the media. Rusbridger is also a retweeter of authority, linking to reads in The Daily Beast, the FT and The Independent among others.

Tweets range from media gossip to full-blown trouble-making, for example: "I never met a Guardian staffer I didn't want to punch. It's not the politics, just awful, awful people."

Episode 5 (First Bit). Since then, however, he has become famous as a comedy Darwinist, and presenter of the irreverent Radio 4 science programme The Infinite Monkey Cage, with Professor Brian Cox.

Sister of Zac and former wife of Imran, Khan is a respected activist on behalf of numerous causes – and now a journalistic force, too. After a stint as associate editor of The Independent, she recently moved to The New Statesman, where her unsuspecting interviewees/victims already include London mayoral candidates Ken and Boris.

Andrew Keen describes himself as "the antichrist of Silicon Valley" – mainly because he's been frequently critical of the notion of web 2.0 and, as one of his book's titles had it, The Cult of the Amateur in creating free content. The London-born Silicon Valley veteran links to key technology reads and maintains a fine line in pithy put-downs. For example: "is there anything more boring than Yahoo?"

But it's for the first reason that most will follow Costandi. His jobs as a neuroscience writer forThe New Statesman and The Guardian mean his feed is full of fun science tidbits – from the workings of the brain to the prospect of test-tube burgers.

His feed is all business, promoting The Spectator's journalism and his own columns, and bringing out the network's political potential – many of his followers are also political figures and commentators. A great source for left-leaning comment digested into Twitter-friendly length: "Depressing to think that Alan Milburn's NHS Plan 12 years ago was more radical and sensible than the dog's breakfast Lansley is introducing."

Thankfully, though, Horgan doesn't use her feed as a PR outlet, it's an often laugh-out-loud, rude, witty commentary on life. A recent selection of messages about a messy children's birthday party is particularly strong in the memory. Also some grotesque tweets about her hamster.

The Associated Press's social media guidelines warn journalists about the dangers of expressing strong opinions (and retweeting others' views). As such, AP's man in London's feed may lack the colour of other hacks' output, but it's still a very useful collection of information – mixing AP news stories with interesting political facts from other journalists in the Westminster Village and further afield.

The bile-fuelled Times writer (and co-presenter of Giles and Sue's Royal Wedding) is a funny, furious tweeter who, when not using Twitter to banter with his fellow restaurant critics, can often be found exploring the outer limits of taste. Coren attracted complaints in 2010 for a tweet jokingly suggesting he might rape and/or murder his neighbours' drum-playing 12-year-old son. Last year he was threatened with jail for contempt of court, after tweeting jokes that might have broken a star footballer's privacy injunction. Of course, neither incident did Coren's follower count any harm whatsoever.

There's a wholesome feel to the recipes and chat, and recently he's made waves by tweeting a trip to Rwanda with Save the Children, investigating food poverty. "I'll avoid the faux profound and go for this: by god, the coffee in Rwanda is good." (February 2012).

Unsurprisingly, he's a keen disseminator of news about the city. Huppert is also co-chair of the All-Party Parliamentary Cycling Group and he's used Twitter as a key part of the group's work on cycle safety – which has been especially prominent during The Times' recent campaign on the subject.

But he's not afraid to share some of the sartorial insight that comes from years of broadcast experience: "u cannot tuck your tie into your trousers if you are older than 9 years old", he told one curious viewer (February 2012). And then there's this gem from last year, when Alan Johnson's resignation was announced: "Johnson out, Balls in. Everyone's a winner?"

Recent examples include: "Morning. Day off with my man today. It's cold outside but it's warm in bed.

Written by a team of mostly female freelancers, the Domestic Sluts feed is – like the blog – a joint endeavour. Much consists of links to blog posts; the rest is irreverent consumer commentary. Recent tweets include: "Off to Borough market this afternoon. We want all of the cheese and a little bit of rain isn't going to stop us." And the sequel: "Cheese coma."
