As rumored it might, Microsoft's new search technology debuted today. Now the Search Wars are fully enjoined. So . . . Go . . . whoever!
I don't have a horse in this race, though I'd admit to a certain fondness (still justified?) for Google. Hopefully, we users will only benefit from better usability and better search results.
It sound like a passive launch, so you may not be able to find the new search engine, but it should start showing up here and there when you least expect it, until it's fully launched.
Update: Or you can just go here. Nice clean interface, that's for sure. Don't know about the results though.
