The MSN interface is just too buggy, but it's getting better everyday. I think they're going to give Google and Yahoo a run for their money. Once they get a better volume of traffic (and the key here is good traffic) they'll really be a viable option.

I think with Panama, Yahoo will really step back into the game, now if they can just get rid of some of their crummy partners, we'll all be happy.
