Ever since the announcement of Microsoft's and Yahoo's partnership, it's around the blogosphere that there's now only one major rival to Google: and that's Bing.
In the deal (the details can be found everywhere on the internet - use Google ;), Yahoo will replace it's search with Bing (and other changes will take place). This means no more Yahoo! (sob).
Is it for the better or worse? Google thinks it's not good (and they have every reason to be threatened, considering how quickly Bing's gaining momentum in it's market share) and MS/Yahoo think it's good (since this is a market controlled by one major player, and the smaller ones don't really stand a chance without consolidation).
What can I say! Good luck to both companies!
