Well not quite, but I came across a pretty great shopping aggregater/search engine from one of my favorite blogs GeekSugar.com. Pretty timely post, considering it was just before Christmas day that I ready the post. The site is www.ShoppingVale.com which acts as a simple search engine pulling results from Amazon, Dell, Target, Wal-Mart, Best Buy, Buy.com, Sears, Comp USA, eBay and Costco.com. The more sites like these that show up the more I feel good about my paid-search argument.
I really do believe you will end having a topical search engines. One for travel, one blogs, one for shopping etc. Just try using Google to search for a Guitar Hero III guitar for the Nintendo Wii. It took me about 20 minutes. Then try using ShoppingVale.com. It took me 2 minutes.
