You may not be a statistically significant sample :)

I for one do all my personal projects in Python, so I would prefer it to most of the languages you mentioned. Python is totally awesome :D

This week I forked the lesswrong codebase, installed all the needed dependencies and tried to get it to run. I still haven't succeeded (it seems it can't find psycopg een though I installed it, this morning before going to work I was fiddling around with PYTHONPATH). I will get it working in the near future and start working on it.

(pjeby, another commenter here, is a major Python guru, though I don't know if he plans to contribute)
