[Twisted-web] Question about the Big picture

I just received a advertisement for a new book "TurboGears", a python web application server. There sure are a lot of these approach/communities focused on python. So what's the 40k foot view of the menagerie. (i understand this question is a bit abstract). Also do we have to start saying Turbo again, I was just getting use to "Extreme" and "On Steroids" as in ExtremeGears or Ruby on Steroids :-) Respectfully, Tony Sterrett Sterrett Software, LLC.
