To demonstrate the vehemence which long-term experience programmers view the lack of ability with which Guido is running the python3 project.

If he had actually addressed the important questions in Python3 (first being getting the majority of people on 3 quickly by getting the major libraries ported quickly, second being addressing the GIl in either 2 or 3 (if the GIL had been removed in 3, I would have much more strongly considered it).

If either of those had been addressed, some of us (who are influential in the area) would have adopted 3 and prosetlyized it. However, I lost so much confidence in Python after the 2 to 3 transition that I've decided to actively non-prosetylize it.
