Ver interesting post memo, thanks very much for sharing this information with us.
Django and web2py are excellent ‘full stack’ web frameworks with similar features and capabilities. Lying if I say that someone has a feature that the other has not, at least to my knowledge, but as mention Gabriel Hurley in the mailing list: “At the point at which the Horizon project first began the handful of folks working on it wanted a Python web framework that would get them up and running as fast as possible. That meant lots of built-in, “batteries-included” features so they didn’t need to reinvent a bunch of wheels; and that also meant something they had at least passing familiarity with. So they chose Django.”
