Wow. Watching an idea spread through the blogosphere is a very cool thing. Glad this is happening on a day when I'm not stuck in classrooms!
Dave Winer posted his idea about a blogging conference this morning. Shelley Powers chimed in with some great posts about the conference here and here. Anita Rowland commented on Shelley's post, pointing out that there's a lot that can be learned about conference-giving from the SF Fandom "cons".
I contacted Dave about the possibility of some collaboration on this related to the grant proposal that Jill, Alex and I are working on (along with Joi, possibly...), and he's enthusiastic.
And it hasn't even been 24 hours since Dave floated the idea. Blink in blogworld and you miss a lot. :-)
