Keep going. Until the important libraries catch up, you should be using 2.7... It's true some important Python libraries still only work on 2.X. And, as someone who's been writing the majority of my real-world production code in Python 3 for over nine months now, I've found it's not necessarily a barrier. So, for those of you not coding in 3 but would like to, what are these missing "important libraries"? What Python libraries do you need, that do not have quality ports to Py3K yet?
