At one time, I thought that outbound links actually drained your PageRank juice. I also seem to recall IBM research coming up with an algorithm that ranked sites as either authorities or hubs, and gave a different kind of positive ranking to sites that did a good job of being hubs for a given search term or terms.

- srean 16y agoThe HITS algorithm that you are talking about isn't used much because it is quite easy to game the rankings. There are some partial fixes to it. If I remember correctly the search engine Teoma was using a variant of hits.
