I knew that yesterday would be fun, but BloggerCon also proved a thought-provoking, consistently involving, fascinating day. I have never been to a conference where there was such easy intercourse between panel and audience: everyone was truly a participant, in the best sense of the word.
Part of the explanation was the generally high standard of topics and panels. But I think there is something more fundamental. Since everyone (or just about everyone — I found one exception) at the conference was a blogger themselves, everyone is comfortable with voicing their views, and is generally pretty cogent in the way they do it. It makes for a very potent mix.
Now the wonderful problem that Dave Winer and his colleagues have is what to do for an encore. Because there certainly should be an encore.
