The choices for this are, frankly, embarrassingly inadequate. They show a clear bias for the HN echo chamber of young 20-somethings. There are plenty of people in the industry - and on HN - who work on boring, enterprise problems, who would choose values way outside of what the range we see here.
Also 2.2 is clearly better when compared to other option, namely 1.1. As a matter of fact, you can fit two 1.1's in a single 2.2, which leads me to conclude that 2.2 is 100% better.
Anybody with experience knows that the x.1 release is more stable than the x.0 version; and x.2 has even further bug fixes. And 2.0 has more features than 1.0, to boot! So why isn't everyone picking 2.2?
Some real data from this poll: HNers are compassionate people - they vote mostly for the underdog number, so the number of the votes are almost equal. (21st minute from the poll 136:138)
