For now, it looks like Google is number one and Inktomi is number two -- and if you take care of those two, because of all the search partners they have you've handled over 90% of your potential traffic.
But with Microsoft building their own in-house search, some day we theoretically will also have them as a big player on their own, when they drop Inktomi as a data source.
