Facebook’s May 18 IPO—which set the market value of the social-networking giant at $105 billion—sparked significant discussion on Twitter, blogs and Facebook itself, with more expressions of skepticism than confidence about the stock's value, according to a report by the Pew Research Center's Project for Excellence in Journalism.

Users of Twitter were the most doubtful, as almost four times as much of the overall conversation from May 14-20 (22%) consisted of claims that Facebook stock was over hyped than it was worth buying (6%).
