To get a sense of how much you really know about the social networking world and the movers and shakers who are actively developing and tweaking it, take a social media quiz. The Big Social Media Quiz over at the Liberate Media website.
A user needs 70% to pass this quiz, and though I know all sorts of minutia about social media, I only answered 50% of the questions correctly. Sigh!
