i've used appengine from time to time @ pitchfork, and it's been great. with the recently relaxed restrictions on uploads, result sets length, and the task queue, and ability to read and process larger uploads, and xmpp and incoming mail handling, etc, i'd say it's in good shape for bigger, more "serious" projects. absolutely capable for smaller projects, too.
