1. The List App
    best in class, future of all things lists.
  2. Asana
    full-featured "mature" software, but content is mostly boring and uninspired.
  3. craigslist.org
    classic list of lists, still relevant in 2015 despite 1995 visual design.
  4. aaronslist.org
    my own foray into the world of lists. inspired by craigslist.
  5. google.com
    glorified way of ordering long lists. large variation in quality of content, but overall worth checking out.
  6. reddit.com
    good content, easily digestible amusement
  7. JDate
    extremely variable content quality, low signal-to-noise ratio, least exclusive of all lists
