For VanaFest, I will be going with Corinth, and we will try to get information back as best we can. We have decided on making some small posts on JPButton with a iPhone Wordpress App during the show. For example, after a Talk Section or an event, I'll put up a little summary and some pics.
Afterwards, we'll head back to the hotel, and from there we will run a CoverItLive chat session. We are thinking of having the open chat while we make a larger recap for the site, and people can hang out and ask questions about the show.
CoverItLive only works with IE and Firefox, and I looked at many options for live blogging from the show itself, but nothing was really feasible. Wordpress from my cell is probably the fastest way to get out information, since I have no idea if a laptop would get Internet access.
As for the aftershow thing, would people be interested in that? It would open up Saturday morning EST, probably around 8-9 am? If people would be up for attending that, we'll definitely get it running.
