Interesting -- I look at Worst Nodes occasionally and saw a flurry of comments on this poll. Hoo boy.
Reading some of the comments, it seems a couple of people got out of the wrong side of bed that morning, especially when you consider the option after the 'person-hours' choice (unpopular with some) referenced Star Trek (that's the original version, you young-un's).
My only quibble with the survey was that you could have offered 'thousands' and tens of thousands' of hours. After developing in C for about fifteen years, I think I finally felt competent. I'm almost there with Perl, after about the same amount of time.
