Cool survey. I can't help but feel like pie charts are a terrible choice for portraying the information, because they imply that a respondent falls into one (and only one) category, and that all the slices add up to 100%. But I have a sneaking suspicion at least some of the people who have used 1.9.2 have also used 1.8.7 at some point. It'd be much more useful to hear the 90% of rubyists have tried 1.8.7, 85% have tried 1.9.2, etc.
Still, interesting data. I have learned that I am apparently a completely typical ruby user.
