Be warned guys, if you have a douche bag friend or random person who clicks it too much, Google will catch on quick and suspend you from doing this. Just happened to a friend of mine, she made about $65 from it but they caught onto someone clicking it a lot and they suspended her account. She didn't get the money because she hadn't set up her bank account on it yet.

Sounds like a good idea. Might be an idea to put the links to your blogs in your signature (saying click on the adverts) and you should rack up a few £s in no time.
