"Now, unlike other aggregators, memigo monitors how popular --or indifferent-- each link is to each user. When you visit memigo you are either explicity or implicitly rating each link that you see. Memigo intermittently compares your ratings to those of other users and then rates links according to how people like you have rated them. It also keeps track of how you and others like you rate individual sites by using your link ratings to rate the author and referring sites. So, when a new link pops up on the news sites or the weblog aggregators, it is quickly rated by the rating of its author and any referring sites."
