No blogging of conference content has happened because the Marriott Courtyard didn't quite anticipate that having a crowd in for an internet conference just might mean a lot of their guests would intend to spend time, well, on the internet. So their system has been fubar'd since our arrival. The only internet I have is in the conference center itself - and then I'm usually in a panel. I'm taking good notes, and I'll post some impressions sometime soon, but it's possible that won't happen until I return!
Best panels so far:
