Adrian in the Google Blogoscoped forums noticed today that Google's "test" search engine got a new feature -- searching for something like "starbucks" will show you some tabs that make it easy to drill-down into to find results you are looking for.
He wonders if maybe they are using Google Coop to determine which tabs are shown above search results -- I am leaning towards "yes". Searching for something like "dry skin" will show you tabs with roughly the same names as the categories on a Google search.
Each time I check out SearchMash , I become more impressed. Every time they change something, I find myself wondering when they will do the same for the real Google search engine.
