I don't develop any sort of web framework or toolkit, so I have no idea which package you mean. I just don't see web2py being extracted from a large successful project, which I think is a partial recipe for success. I'm especially confused, because it's an "enterprise framework", but grown in a university.

We already have a full stack web framework with an insane amount of documentation - Django, and I would bet my money on its continued evolution and 1.0 release. If anyone is on the fence, look at the web2py/gluon source code and ask if that's the sort of full stack you see being maintained by a community.
