Squidoo - Is a pretty unique community site allowing you to earn a share of the advertising revenue generated by people visiting the page you created. Whether it's a review of a book, restaraunt, night out or a rant, if it attracts visitors you'll get income! You can even use it to signpost your website and increase SEO (search engine optimisation).
For an example you can visit the page I made about Absinthe
If you sign up via my referral link you will also earn an extra $5 when you have earnt $15 revenue through visitors either just viewing your page and more if they click through from links on your lens (squidoo call each entry a lens)
There is no limit to the number or subjects you can create pages on and payouts are monthly via paypal. The minimum payout is actually a ridiculously low $1
I'll report back in a few weeks to let you know how I get on with it and what sort of earnings I have made. I don't expect to make bucket loads of cash, but I'll see if I can make some interesting content and what sort of things I have found worked!
