Two "Must See" Presentations From Web 2.0 Expo

I was fortunate enough to have attended on both Wednesday and Thursday (I presented some new content at the unconference part of the show, Web2Open – organized by the PodCamp folks).

1. Baratunde Thurston discusses the power of the hashtag in Twitter and in telling stories: Web 2.0 Expo NY 09: Baratunde Thurston, "There’s a #Hashtag for That":

2. Chris Brogan discusses something he calls, The Serendipity Engine: Web 2.0 Expo NY 09: Chris Brogan, "The Serendipity Engine":
