I saw this post last week. Looks like Yahoo may be getting back into the search game. They have two projects “Fast Break” and “Curve Ball” aimed at developing a mobile focused search engine.
Now how a “mobile” search engine differs from a “desktop” search engine beats me. But given all their work on improving the mobile interfaces for their sites, I suppose it makes sense. It would be nice to have another big player in search. Maybe help keep Google on their toes.
