Regarding adoption, it's 3.0 that's obsolete, and 2.7 that's vibrant. Even for new code (they conveniently only count totally greenfield projects, but most new code is written in fact to work with established 2.x codebases under Python 2, not as a totally greenfield project).
What numbers? All the numbers I've seen -- official numbers from PyPY etc) tell otherwise.
Also, your anecdotal data is arguably biased as well.
My take is that many sources, including the ones linked to in the tweet's replies point to solid growth in Python 3 adoption. Python3 might not have overtaken Python 2 overall, but it's very far from being "dead".
I wasn't making the point that Python 2 is dead, in fact quite the opposite. I'm saying that with this many users the adoption rate is too slow. There is no real reason for people to switch. Until there is that incentive Python 2 will not die.
No, I asked for a representative data source (representative was implied: a biased data source is as good as no data source at all).
