How far in the realm of fantasy would a voting system be? I realize you guyses first priority is "stuff the site needs" rather than "stuff that would be nice to have." But I often find myself holding polls and the like to see what my followers want me to draw next. However I usually only get about 1/4th of my follower base to vote as people don't like clicking through to offsite voting polls and all that. Maybe it's just wishful thinking.

Well, we are working on a poll system that can be used in posts, so possibly not as far off as you think!
