Umm … I know I’m not alone on this, but mashups via Open Social are very cool. Trying to use Google apps and hoping that’s a good place to create some mashups for business. I’m also in an beta mashup-app-building tool.
It seems that Pownce doesn’t really have any of my facebook or google friends, but just randomly suggests people with similar names. At first I thought this was stupid, but then I recognized how hard it seems to find old friends or relatives when you don’t have their latest e-mail.
