Does msn/Inktomi use Google PR?

My msn traffic steps after the Google update

[growing]

During the last few Google dances, my level of traffic has changed significantly from Google (no surprise). But my traffic from msn.com has also stepped up or down a couple of days later in the same direction.

But doesn't MSN use Inktomi? The incoming links are obviously different from Google, and obviously a lot older. So why do I get a step in msn.com traffic after Google dances?

Does Inktomi/MSN use Google's page rank (perhaps by trawling the Google directory)? Or is this just a coincidence? Has anybody else noticed this?

I doubt it. However, I notice Ink has the SERPs most like Google. Thus, if Ink is trying to imitate Google's algo, then if Ink is updating soon after Google a site that went way up on Google might also on Ink.

Inktomi does NOT use PageRank. They have just finally gotten better at spidering / updating / including more in their database.

Any major SE simply has to use links in some fashion or another in a modern algorithm -> the strictly 'on page' ones are too easy to manipulate.

Really? Interesting. Fast and Google track a lot closer for the stuff I look at. Inktomi, while still relevant, is out in left field somewhere.
