Go to http://www.easyhits4u.com/?ref=atticanibal 

Make an account. It is a traffic exchange site but it is the BEST one out there. You have to look at someone else s site for 20 seconds and you get 1 credit which you can also use for others to look at your site.

But you can just keep it running while you are chatting on facebook and every 20 seconds or so you check the page to click continue. 

It;s a great way to get your site visible or to drive other people to your ppc gpt sites :)
