Maybe you can do a search of 'MSN Zeitgeist' in Google I mostly use Google then Yahoo for searching. I only use MSN when Google and Yahoo's site is down...
I use googs but msn seems to give my site more quality organic links than google at this point in the game. So that shows you that MSN knows who's the man and google just hasn't figured it out yet so maybe i'll start using msn a bit more. idk google can be a little stuborn at first. they like old sites.
I use Google most times because of Google's localized servers I also some times use MSN when the Google's result are irrelevant
Google all the way. I am number one in MSN for a lot of good keywords. It doesn't bring much traffic, if any.
I use Yahoo and google for rankings(pr with the toolbar) and sometimes MSN, trying to use MSN more to try to find more links there. cindy
