Search Me

After months of speculation, the top-secret Amazon.com venture A9.COM unveiled a test version of its new search engine–well, sort of new. Searching the site calls up results from Google while simultaneously finding books on Amazon. Here’s what’s new: for each site your search uncovers, A9 spits out a list of related ones based on what other people liked. It’s similar to what Amazon already does for books–and A9 hopes it will become just as popular. –By Joshua Macht
