There are plenty of places that provide you of aggregated lists of what’s being popularly-searched out there on the Internet. SearchQuilt, at http://searchquilt.com/, goes one better by listing what’s being searched for and then gives you a nice one-page meta-search for them.
The front page lists popular searches from places like Yahoo, Google, and AOL. (There’s also a year-end hot searches column.) Every listed search is hyperlinked. Click on an item and you’ll get a full page of search results from various places, including blogs, auctions, products, news, and the Web, of course. I was surprised at how well this worked with even more generic searches (like “Hairspray”.)
Sometimes one of the items on the big search result page would take a little extra time to load, but this is a fun site — plain but extensive. How about adding Icerocket top searches?
