This new search engine beta actually will work with a lot of English keyword searches in addition to the Japanese. Enter a keyword and give it a try.
The tabs at the top offer a number of ways to break down the SERPs. The default is to show all of the different categories together on one page "zenbu". Then we have web, Q&A, images, movies, news, maps, shopping, and sponsors.
I've run through several searches, and it looks like a useful way to break down the SERPs. Could this be part of the MS Kumo [webmasterworld.com] beta?
