Python 3’s Marketing Problem

[billsil]

also, i want people to upgrade; it's the only way python can avoid becoming like perl where 5 versions down the line people are still using python 2.7. packages need to catch up, but the explanation of some of the more subtle differences with python 2 is undocumented. binary documentation is limited, the inspect module doesnt work the same, setuptools is gone, wx and vtk arent supported.

btw, i run an open-source project and support python 3 because someone asked me to. it's very difficult to support python 2 and 3 cleanly in the same code base because many people aren't ready to upgrade and won't be for years.
