Become.com’s claim to fame is that it’s the “first vertical search engine to combine product-focused Web search wit comparison shopping.” While vertical search engines (limited to specific areas, such as shopping) have existed for quite a while, they’ve oddly never been as good as their more general counterparts.

Having just launched a visual upgrade, everyone at Become is more excited than ever.
