DevX has just posted Rapid Java Web Application Development with Tapestry. It's a very fast paced intro to Tapestry and is balanced (yes, Tapestry does have its share of quirks!).
I've been doing my best to push Tapestry over the top for a couple of years now, ever since I left my last full time job and became a consultant. Tapestry really feels there, with more and more people jumping on the bandwagon (in a positive way).
Even here in Portland, I've already met with three different organizations that use Tapestry exclusively and love it. It's another sign that moving away from Boston was good for body and soul.
