Pagerank Explained. Google's PageRank and how to make the most of it.

Pagerank Explained. Google's PageRank and how to make the most of it.: "Not long ago, there was just one well-known PageRank Explained paper, to which most interested people referred when trying to understand the way that PageRank works. In fact, I used it myself. But when I was writing the PageRank Calculator, I realized that the original paper was misleading in the way that the calculations were done. It uses its own form of PageRank, which the author calls 'mini-rank'. Mini-rank changes Google's PageRank equation for no apparent reason, making the results of the calculations very misleading.

Even though the author abandoned mini-rank as a result of this and another paper, the original, unchanged paper is still available on the web. So if you come across a PageRank Explained paper that uses 'mini-rank', it has been superceded and is best ignored."

This is interesting, I've been looking around to get some ideas for our blog. Haven't started yet. I'm hoping you can give some advise. Here's my topic and website. Please take a look.

Come and check it out if you get time :-)
