Interesting comparison from 1998:<p><a href="http://slashdot.org/poll/421/My-Age-is" rel="nofollow">http://slashdot.org/poll/421/My-Age-is</a><p>In 1998, 22% of respondents were ages 16-20, 53% were in their 20s, 15% in their 30s and 5% over 40.<p>As of this writing (and assuming that I did my arithmetic correctly), ~7% of respondents on this poll are ages 16-20, ~60% are in their 20s, ~25% in their 30s, and ~7% are over 40.<p>Obviously there are a lot of caveats here, but the slight increase in the overall age of techies between these two polls is nothing like you'd expect if everyone who started in their 20s in 1998 stuck around until today.<p>*edit: fixed arithmetic error. D'oh!
