http://750words.com/ is my new favourite website and the best distraction for a good few minutes every single day.
The goal is to write at least 750 words every day. It can be anything you want. I'm using mine as a sort of journal for when I really need distracting. You can take part in the monthly challenge. You basically have to write every day for that month and if you do it, you get your name on the wall of fame. If not, you go on the wall of shame.
You also get badges for your page for writing after doing a certain amount of words, or doing it every day for a certain amount of days or writing without being distracted and more.
You also have your own page which tells you how many words you've written in total, how long you've spent writing etc. It also analyses how you might be thinking/feeling etc by the words that you use and puts them into pretty little pie charts and stuff.
It's pretty great if you're a writer of any kind :)
