it's hard to tell how useful it is, link building always takes time but their plenty in it and penty I don't know. So I've learnt something at least. It's good for organising your link building though. As far as I know it's Paul Smith (http://www.affiliates4u.com/profiles/Paul Smith/) behind it. All the example on the blog are for Gift Guide Uk and thats where payment goes (paul smith).
