I am not much into web development, but my impression is that there's nothing very much innovative in the Python's tools. It seems a lot of the path was already laid by rails and friends, and they did so well that Pythonist implemented similar ideas. That is not to say they are bad frameworks, just that catching up is not a good reason to drop what you know and move to Python. On the other hand, there are people who don't like to be on the cutting edge. That is true. But then those same people will probably be more comfortable with PHP: it's been around a lot longer (and they probably already know it), and there's a lot more support and web tools around. So Python for web development neither attracts those on the cutting edge nor the conservative people. I imagine that people who are in the middle may like it, but it's not something you can advertise much about. Of course I can be completely off track: as I said I am not much into web development. (incidentally: I am sad Ruby doesn't seem to have much adoption in the scientific community which seem to be mostly behind Python... sigh... ^_^)
