I like Jason Calacanis. He's done a wonderful job with TWIST, the This Week In network, the Open Angel Forum and the Launch conference. I find him to be very funny and entertaining, passionate about entrepreneurship, tough-minded and determined to succeed, forthright and honest about his opinions, and someone who isn't afraid to make hard decisions. I do wonder about the future of Mahalo, though. Unlike some of Jason's other ventures, it seems as if Mahalo - now version 4.0 - has struggled to obtain a unique and strong identity, let alone sufficient market traction, so far. If it can be the best how-to video site on the Internet, great, but given Google's recent stance on how-to content sites (i.e. the 'farmer' algorithmic change), not to mention all the other companies vying to be the best how-to video site on the Internet, the company certainly has its work cut out for it. On the other hand, these are precisely the circumstances that sort out the real entrepreneurs from the wannabes and from Jason's comments above... I wouldn't count him or the Mahalo team out.
