I downloaded it when it first came out, but didn't start using it until very recently.
  1. The community is amazing
    I can't remember the last time a group of users were so positive and supportive of each other. It reminds me of what metafilter user to be , or my early days on sweetaddy 15 years ago.
  2. It is intimidating
    Trying to come up with lists that meet or exceed the quality of lists that people post is anxiety inducing. Everyone is so witty. You can fake it in twitter, but here it is the real thing.
  3. It is addictive
    Ever since I started using it I can't stop checking it and reading lists.
  4. It is so well designed
    It has every feature I want and nothing that I don't need.
