Pete, you're leaving out some very influential factors, because Hitwise estimates traffic to a site, not searches on a site. There are many more reasons to visit MSN than just search, whereas Google is primarily about search. Hence artificially spiked MSN figures.
Hitwise uses recorded data not estimations.
I'm not disputing those facts. When did I ever say the search facility was as well used or it delivered anywhere near the traffic that Google does? I didn't.
I pointed out that Google is clearly far better at its job!
Interesting that all these people are already arriving at MSN though isn't it...
