Hi, I came across this when I was working for a marketing agency a couple of months ago. They used it to dive traffic to their website, I think its a good home based business opportunity because they pay per click to people that refer their products and services. Effectively, if you've got loads of friends on Facebook/Twitter etc then all they do is promote to their followers and they get paid if people click on the links. The great thing about this is that people only refer the things they like. They were featured in the press last week as the biggest challengers to Facebook and Twitter in the battle of social networks. This is the website, http://referr.co
