Agreed. More and more important libraries are being ported to Python 3. I'm working on a web app supporting Python 3.3. I keep it backward-compatible with Python 2.7 just in case I would badly need a library that hasn't yet been ported to Python 3 but it hasn't happened yet and I have good hope that we'll be able to deploy it on Python 3.3. I develop and test locally with Python 3.3 and travis runs my tests against both Python 3.3 and Python 2.7. Every time the Python 2 build breaks it's because of some silly unicode-related problem that has been fixed in Python 3, so it really motivates me to develop with Python 3 from now on.
