Bitter widgetmakers may want you to believe venture capital for the Facebook platform is all dried up, but don't believe it. Not when there's visionaries like former AOL CEO Steve Case still around. Case has joined a $5 million funding round led by Grotech Ventures for widgetmaker Living Social. Living Social builds apps like BookSocial and BeerSocial for Facebook, MySpace, Bebo, Hi5 and Orkut that recommend products for their users based on their friend's tastes. On second thought, Case's investment may be the clearest market signal yet that investment money for widgets is soon to disappear altogether.
