1) is so great -- thanks for making/sharing. I run into the clunky search process for 10k's once in a while and think your site does a great job improving that experience.

In case you're taking feature requests, these are some things I'd love to see in a 10k site (order in relevancy):

  autocomplete in search
  see recently released 10k's
  browse functionality
  10k specific discussions (e.g., annotating similar to RapGenius as well as longform analysis)

Some/all those may not be relevant for your site, just things I've always thought would be cool to see. And again, nice job with the site!
