Over Fifty

I like to try new things...like attending Li.st Live in Brooklyn!
  1. I wonder how many users of Li.st are over 50?
  2. I wonder if they have an analytics team?
  3. I wonder how someone who's analytical can be creative and use this app to make others laugh?
  4. I wonder if I'm using a question mark correctly? I should text @dfly, he would know for sure!
