I didn't see this search engine listed on the info page, so I thought I'd mention it. I've been using Blingo to search the web. It's just like searching at Google or Yahoo except Blingo gives away prizes, like iPods and PlayStation Portables. Check it out and sign up as my Blingo Friend. If I win, you win too!
My friend won an iPod with video a few weeks ago, and she is constantly winning iTunes gift certificates and movie tickets. I just signed up a couple days ago so I've yet to win anything, but hopefully we can win stuff together!
