Why is no one talking about ActiveGrid, which at least on the surface seems to be the most polished way to build web applications in Python so far. They have a sound financial backing, $10 million when I last heard, made news on non-Python circles, have a relatively friendly authoring environment and are probably addressing the enterprise more specifically than any other web framework.
It somehow did not grow on me but I would love to hear what others' experiences are compared to other frameworks they use. -- http://mail.python.org/mailman/listinfo/python-list
