on an aside, at Web 2.0 New York yesterday every speaker payed homage to Jeff Pulver (Pulver.com) as if he is the God of Social Media. Congratulations to Jeff (he must have done an exceptional metamorphosis while I wasn't looking), when I last followed him he was the God of Telecom. I will have to start reading his blog and Pulver.com to see what all the buzz is about.
When they weren't praising Pulver...the buzz (overhead his name mentioned throughout multiple conversations in the audience) was all about Jeremiah Owyang (Forrester Web 2.0 analyst), whom I only recently discovered. Apparently I am the only one in the space who did NOT know about Jeremiah. If you want to know Web 2.0, I can not recommend Jeremiah strongly enough. His blog is here.
