BrowserRank from Microsoft

Well, this is pretty interesting.

It seems they want to include 'time spent on page' as one of the signals, or rather, the main signal. That's good, but I can't help worry that it's self-fulfilling - that is, those pages near the top will naturally have the most time spent on them, since people tend to click near the top first. Therefore, bad results may find it hard to slip down the rankings.

But Microsoft have some smart people, so we'll see.
