- You need to restart the server to reload code
- I don’t really like the templating language as much as Kid or TAL
- It doesn’t have enough polish (documentation, examples, nice web presence)

That said, if I have a need for Twisted I’ll generally be using nevow (or even just twisted.web).. but that’s not really an option for most people. I can’t go to a freelance developer who is mostly experienced with something like PHP and tell them to use Nevow and expect them to make a deadline… but I think there’s a chance that I could with something like TurboGears (with a little help on Kid and Python syntax) given the excellent documentation and the “target demographic” being more than just hardcore Twisted hackers :)
