I'm still writing lots of code with it and even quite a lot of new code. It's been around for ages and it feels like almost no libraries have been ported to 2.x yet. On a couple of occasions I've started a project with Python 3.x just to drop it or move to Python 2.x as a library I need doesn't seem to exist for Python 3.x and I don't want to port it over myself. I've never had this issue with 2.x (no libraries support 3.x only.)
Most Python 3.x "killer features" have been back-ported to Python 2.x and I honestly feel little reason to upgrade myself now. When support for Python 2.7 is officially dropped we could fork it and continue. I would hope it wouldn't take huge amount of effort for some people to support it? Just fix bugs and security issues and take pull requests? In that way might Python 2.x even outlive Python 3.x or at least remain more popular?
