Missed opportunity: Current TV founder Al Gore dropped in on the start of Friday's "Hack the Debate" event, a partnership with Twitter. Attendees were invited to post updates to Twitter during the debate between Barack Obama and John McCain. Current flashed selected tweets onto the screen over a live feed of the debate. Wired dubbed it groundbreaking. Social media consultant Shel Israel complained the result was "just a bunch of young people making shallow comments." But either way, where was Gore?

After giving a short speech to attendees, in which he praised their efforts to break the "feudal" system of network television, Gore promised "By tomorrow, I'll be on Twitter." Then he left. Come on, Al. How hard would it have been to sign up for Twitter on the spot, then stick around for a few minutes to lob an inconvenient truth or two across John McCain's puss during the opening leg of the debate? Instead, here's the message Gore sent: Twitter is for kids. (Video by Laughing Squid/Scott Beale)
