Twitter shares climbed to a near all-time high in New York trading yesterday as investors cheered a series of new products introduced by the social media giant.

The stock jumped by more than 9 per cent to $49- rallying ahead of rivals Facebook and Google- and hovering around it's all-time high of $50.

But Twitter founder Jack Dorsey couldn't care less since he "never" checks the stock price.

"Actually it's not something I pay attention to at all. We have an entire company of brilliant people making the service every single day," he told CNN's Piers Morgan in a television interview.

"It's not the leading indicator of success. The leading indicator of success is people finding value on the service, using it."

The British presenter then boasted about having more followers than the founder of Twitter himself.

"Are you aware of how many I have? 3.8 million. Nearly double the founder of Twitter, you have no idea how satisfying that it," he said.

Dorsey also discussed Twitter's privacy policy in the wake of the NSA spying scandal insisting that the social media giant wants to "defend the people using the service".

"The nice about Twittter is that it is inherently public and there is an understanding that when they tweet something the world sees it"

His comments come after eight of the world’s leading technology companies, including Apple, Microsoft, Facebook, Google, Yahoo and Twitter, called on the US government to implement sweeping reforms to the country’s surveillance policy in an open letter.

The group said they understood the government's concerns and duty to protect its citizens but insisted that Edward Snowden's spying revelations highlighted the "urgent need to reform government surveillance practices" worldwide.

“The balance in many countries has tipped too far in favour of the state and away from the rights of the individual — rights that are enshrined in our Constitution. This undermines the freedoms we all cherish. It’s time for a change,” wrote the group in an open letter published on Monday.
