Do you think you can manage for a day without Google? This is the challenge being set out by Alt Search Engines, and they're providing you with a a list of different options. I've got a couple of collections of my own you could take a look at - there's the 'Which Search Engine When?' page or the collection of 130+ search engines on my Web Search Engines page.
I'd be really interested to see what sort of experience you have, or indeed if you simply can't cope with the idea of not using the Big G for a day.
