Twitter valued at $3b

Twitter is reportedly planning a new funding round that would value the social networking site at over $3 billion (€2.2 billion).
The company is in talks with investors over the financing, and has drawn keen interest  from a variety of firms, multiple sources told Silicon Valley blog TechCrunch.
Twitter is apparently eager to raise more than the $100 million the company took during its most recent fundraising a year ago. It has collected $160 million so far.
Russian investment firm DST Global - which has stakes in social networking companies Facebook and Zynga - is eager to lead the round, the sources said.
Secondary trading for Twitter shares issued to employees value the company at a minimum of $1.57 billion, TechCrunch said.
Twitter is also looking to add value by stepping up sales of tweet streams. The firm unveiled a deal granting start-up Gnip permission to sell its data feeds to developers yesterday in a bid to address complaints that its pricing seems arbitrary.
Gnip will offer feeds in three packages - the Halfhose, which comprises 50% of tweets; Decahose (10%); and Mentionhose, which includes all posts that mention a particular user.
Twitter currently only sells an entire feed of tweets called the Firehose, All Things Digital said. Its 10% Gardenhose feed has been replaced by Gnip's offering.
