I was reading an SEO book that I have that mentions the website SearchMash.com which is owned by Google. I checked the url and it says "SearchMash has gone the way of the dinosaur". What the heck was SearchMash.com and why did Google shut it down?
Not sure but I found this: http://www.techcrunch.com/2008/11/24/why-did-google-discontinue-searchmash/
In my opinion, I think Google have done testing all the new changes and they don't need it any more for now
