Factual Correction
Kevin Werbach has reminded that Dave Winer was one of the first speakers at Supernova 2002.
I remember Dave getting mad at Dan’l Lewin and all sorts of scenes out in the hallway. That’s when I first met Cory Doctorow and all sorts of other players - who have now become familar faces. In a lot of ways, that conference was the beginning of Web 2.0.
Here’s Dave’s posts, Sifry’s and Doc’s.

What kind of scenes?
I didn’t get angry with anyone, ask Dan’L Lewin, he and I are buds.
Listen, Kevin doesn’t like to have people talk about how much money he charges for keynotes. Welcome to the blog-o-sphere where someone said “we fact check your price list.”

My public notes http://www.thebishop.net/geodog/archives/2002/12/13/great_oneliners_from_supernova_2002_day_one.htmlfrom that day are sparse, but I remember either Dave or you Marc yelling at Dan’l (who I worked with 15 years ago) from the back of room about whether Microsoft was going to open the schemas for Office XML formats. It was pretty heated, but I think it was you, Marc.
I’ve been (and will probably go again) to both ETech and Supernova, as well as bloggercon and Mashup Camp, and I do think that both of you are doing a public service by forcing the issue of paid placement out into the open.
