This is interesting:
From TechCrunch
People already ask a lot of questions on Twitter, but it is not designed as a structured social Q&A site like Quora. But that may change judging by a talent acquisition of the team at Fluther, a social Q&A service founded in 2007 that raised $600,000 from Ron Conway, Marc Andreessen, Ben Horowitz, and Naval Ravikant. Terms of the deal were not disclosed, but Twitter did not buy the Fluther product or shares of the company. Rather it entered into an agreement with the five-person team to join Twitter in return for some sort of compensation to Fluther’s shareholders.
Could the team have indentured themselves to pay their backers?
