It’s hard to believe that last week’s Health 2.0 conference was just the third annual installment of the event. The phrase, “Health 2.0” entered our lexicon at light speed and seems to have been there longer than those few, short years. The conference has become a must-attend for hundreds of people, dozens of companies and a hodge-podge of innovators, consumer activists, and buzz trackers.The Twitter feed from last spring’s Boston event rivaled that produced by the Octomom (well, not quite), and had the wireless carriers supporting last week’s event not sustained a massive H1N1 attack, that feat would have been surpassed easily. Heck, even Aneesh Chopra, our nation’s first-ever CTO, was there to kick it off. Congratulations are in order for the conference organizers, Indu Subaiya and Matthew Holt, but going forward they will have their hands full attempting to manage the wild growth of their event.
