Not a shock. Polls don’t seem to have translated in the move to Discourse, but thankfully Zeldar did a tally of 563 votes near the end of this 2010 poll. Aside from the much larger general population back then it tallied 130 posters as 20-29 - any of them left are now definitely over 30 
. There was a grand total of five teenagers - even back in those days the largest group were the over-40’s. There hasn’t been an enormous amount of new young blood since then.
