I have recently come across an interestingw ebsite for bloggers. It is called Reviewback.com. The aim of the site is that fellow bloggers can review each others blogs and therefore provide awareness of other similar blogs as well as increasing page ranking by having more links to their site. This seems like a great alternative to just swapping links. I find that my links list is getting far too long and I cannot imagine anyone really scanning through to see if anything interests them.
