Have you seen www.a9.com? That is A Nine. If you haven't check it out. Its a search engine, with perks. When you first visit the site, it looks a little confusing, but don't despair, search for something. Then after you've searched, it will return the results. On the far right hand side is a thing called columns.

There are tons of columns available, you need to create a quick profile to customize which you see. You can then turn on and off those columns on demand. It is all done with Dynamic HTML, and CSS. So your search term is now able to search many sites all at once.

Give it an honest try. I like it so much at this point, I may just make it my starting homepage. Enjoy!
