No I will not join Ciao because I do not have a bank account in the UK and besides that the payment is not that good.
The idea is good and since you not have to risk your own PageRank when you write stories on your own blog, I would have done it if they paid better money.
But the idea is clever to get people to write reviews on your site for different products and get more hits from search engines.
The information on how really get paid is a bit long and to many ifs and but. But if you have nothing else to do then write reviews about televisions sets and DVD players this site is for you.
