I'm using Python 3.4. All the libraries I need are available, including the world's best database library, SQLAlchemy. It's a more pleasant experience than Python 2.x. And I have the peace of mind knowing that I'm not stuck on a legacy, deprecated platform.
I used to stick up for Python 3 on HN and other places but I've given up. I have no interest in converting people going to Go. And no matter what Python (or any other language) does, they are going to lose users to JavaScript.
Also, my experience is that people who feel passionate about Python 2.x will shout down people who are using Python 3 with "nobody uses Python 3." Who has time for that?
