Show HN: Just Write, a "weekend" project in time for NaNoWriMo

I actually started working on it for last year's NaNoWriMo (National Novel Writing Month; http://nanowrimo.org) but life happened and it got shelved so I pulled it out again today and got it into somewhat usable shape.

Sorry about the FB login, I know I will get shit for that but I need it because I eventually want to add social features :)
