Just read the post http://lion.taoriver.net/?p=10 which gives some quite negative feedback about TurboGears. I think he has some valid points about documentation: it's perhaps given the impression that TG is already very easy to get up and running even for (python/web app) novices, and maybe some info (like standard template variables) needs further explanation.
Of course TG is still bery much in its infancy, but is this something that visitors to the site should be informed of ?
