SearchMash, the New Google?

Google usually runs all kinds of experimental user interfaces, changes to ranking algorithms, and tests of every type on their own site, just letting a very small percentage of their users see the changes and then evaluating the response. Now, Google has actually launched its own experimental search engine a a completely different URL with no Google logo. SearchMash is the new site. SearchMash presents Web results with Image matches off to the right side. Results are numbered (something I always prefer) and can be sorted. Just click and drag one to change the order of the results (although I have no idea why you might want to do this). Another interface change is that at the end of the page, searchers can just click on the "more web pages" link to retrieve another ten results. Instead of being shown on a new page, they just appear below the first ten, on the same page. Overall, I find no compelling reason to use this, but it is a site to watch for future Google experiments.
