A writer friend of mine pointed out 750words.com to me earlier this week. It's a really basic website that just puts out a simple challenge to it's users: write 750 words a day about anything. It doesn't care if you just type "I can't think of anything" a hundred and fifty times, it just keeps a word count, lets you know when you've hit your mark, and gives you points for doing so (Yay, points!). The idea behind it is that once you've gotten yourself started writing, you can continue doing so.
