Welcome To RailsConf
I'm nearly at the end of day 1 of RailsConf, and I can report that it's very, very crowded. The sessions have been great. You can follow along with me and my day at http://twitter.com/noelrap for the minute by minute updates, I've been posting there fairly regularly. I'll do a fuller recap of the conference at the end.
If you are at RailsConf, remember to come up to me and ask for a book, I still have a few to give out. Also, I've scheduled a Birds of a Feather session on Saturday at, I think, 8:30, to talk about iPhone and mobile web application development using Rails, especially to talk about the rails_iui plugin.
