Just saw that Howard Ship is going to be in town (Philadelphia) for NFJS and presenting on Tapestry! Good stuff.
I can't make NFJS Philly, but it will be exciting to see how Tapestry takes off with Howard making the rounds plugging it. I think for highly interactive web applications Tapesty is an amazingly strong option right now. I got to meet him at ApacheCon and he is very much on the ball -- sit in on one of his sessions if you go!
