Just finished with web 2.0 expo (SF). The conference was not well attended, probably the result of bad timing (right after SXSW) and a name that was AWESOME in 2007. That said, here are two of my favorite presentations. There were others, but the presenters haven’t posted the slides. 1. Cindy Alvarez, “But How Am I Doing Compared to Other Companies?” If you do any A/B testing, conversion optimization, or direct-response online advertising then you will find this useful.
