A little late spring cleaning going on over at the Google Campus with Google sweeping SMS search right out the door. The search service was killed off on Friday without so much as a fare-thee-well from Google. Looks like another case of 'if you don't use it, you lose it'. It could be that Google is simply doing this to stay one step ahead of the times. Or it could be that, as with other products like Google Reader, it was not getting enough use of the service.
