Microsoft takes others ideas and does them better. At least that’s what some claim, and now they are out to show Google how to do PageRank better. That shouldn’t be too hard as PageRank numbers are flawed anyway. Microsoft’s ranking system is based on user behaviour. The more clicks and user actions they record, the better your site ranks. Live.com, Microsoft’s search engine, has millions of users so they think they can deliver some useful ranking numbers based on this model. While the idea isn’t new to this planet, it does seem to be what people want.
