750 Words - a site to help you keep writing

The blog at The Office of Letters and Light posted an entry mentioning a site called 750 words. It features a text editor that counts your words as you type, but that's by far not the coolest part about it. It grants you award badges for achievements, like writing to your 750 word goal multiple days in a row, or writing without allowing yourself to stop before you get to the goal. Not only that, but it has neat stat trackers that monitor your performance over time, as well as gizmos that judge your state of mind while you write. I used it this morning to write some more of a story I'm working on, and, as the scene was very tense, involving an argument about someone's death, the gizmos declared my state of mind was 'upset' and that I was most concerned about 'death'. Not, at this point, useful information about myself, but still pretty cool.
