It's a site where writers can share and promote their work. I'm well aware of the dozens of writing communities out there, but most of these sites operate in a forum or blog model, which I find rather difficult to filter good content/writers from the bad. The voting process on Lit is modeled after a Markov chain where every writer has an assigned global rank. I'm hoping the competitive nature of the site will motivate people to submit their best writings. Eventually, I'd like to make this the destination where aspiring writers post their work and get discovered.
This is one of my first Rails apps with the user profiles powered completely by Facebook Connect. I used the Facebooker (http://facebooker.rubyforge.org/) plugin, which was relatively painless to integrate into my app.
