David Dayen (dday) and I just did an interview/conversation with Van Jones. dday, who writes these up far better than I do, will be posting a synopsis at Calitics and over at Digby's place. I'll be updating with links when he posts it.
In the meantime, I've posted a diary on DailyKos with some pictures of the big tent and its happenings. You can check that out here.
