Please tell me someone has pictures of Seesmic founder Loïc Le Meur giving small-time technology investor Michael Arrington Segway riding lessons outside 330 Ritch for the TechCrunch50 conference's closing party. For now, I'll have to settle for Siqi Chen, left, and Alex Le, right , the guys behind Facebook widget Friends For Sale, at the Plista party at Fluid. Where's the afterparty? It's not at the W or the Four Seasons. Maybe Mahalo chief Jason Calacanis is drinking responsibly tonight and has turned in early, but I'm pretty sure Arrington is up drinking scotch somewhere.
