Once every now and again @age_pollbot posts a poll-- are you older or younger than x age
Where x age is chosen from a normal distribution of adults in the world
Publishes stats after the closing of every poll
People can answer, or not
there could be some good data there, maybe
JFS: Not really. I MAKE friends. They're toys. My friends are toys. I make them. It's a hobby.
