Hey fijal. Agreed that the survey has a self-selecting audience, I'd also argue that they're the more forward-thinking folk rather than jobbing background users.
Back in April 2013 (the last time I saw python.org download stats - where did they go?!) I wrote a blog post noting that fresh downloads of Windows Python 3.3 were greater than downloads of Windows Python 2.7, for 3 months running. Windows is useful as Python isn't bundled (unlike e.g. Linux and Mac). I presume this trend has continued but have no firm evidence either way: http://ianozsvald.com/2013/04/15/more-python-3-3-downloads-t...
