A few months ago I attended PyCon SG (Singapore). At some point one of the presenters[1] asked for a show of hands how many people were using Python 2, and how many Python 3. The ratio was about 10 to 1 in favor of Python 2, with hundreds of respondents.

Python 3 just doesn't have traction, and it may never get there. It's sort of a shame how Python 2 is now in maintenance-only mode, but on the other hand it's great for professionals: we don't need to worry about the language or the reference implementation changing ever again.

Periodically I check my requirements.txt with https://pypi.python.org/pypi/checkmyreqs, but there's usually at least 7 or 8 minor packages and 2 or 3 major ones that are unsupported.

I don't really mind moving my own code to python 3, but I'm loath to move working library code.
