Several weeks ago some people stubled apon this site called SearchMash. After doing some research on the search engine they noticed it was a google owned ip address. Soon after Google confirmed it was there new testing area for there future search engine.
My good friend daveN has a little writeup about how he hates it.
I think the searchmash is pretty good but daveN makes some great points about why it sucks. If you like his post give it a digg on the button above.
