1. To learn about "regular" people and not just follow celebs (don't be "that guy")
  2. Because I heard at least 2 interviews of him promoting list and then I joined (sort of a I scratch your back, you ... thing)
  3. Because I have zero followers and really really really would love to be able to say that @bjnovak was first to follow
  4. Because I had a completely shit day and it would just turn it all around
  5. it will give me incentive to come up with some buzz worthy lists (I'm not exactly as funny or charming as @mindy — ok not even close — but I'll do my best)
