Pfft, yeah, good question. Its typically full of incessant babble about the 'awesomeness' of cake with intermittent self-gratification by the core developers. Worthless I tell you!!!!!
cakePHP is a solid competitor to Rails, but the documentation is lacking. Go to the IRC channel for help and get, "Have you tried searching google?"... uh, yeah, thats why I'm here. Additionally it seems like there is just one guy, phpnut, working on the development side... scary.
