If you’re used to Google and nothing else, you might be in for a shock. Kartoo certainly isn’t the fastest or plainest SE available, as it’s constructed using Flash and displays results graphically. I’m still working out exactly how it works, but it appears to display links between web sites and allow you to add or remove keywords before performing additional searches. It looks like an engine that it would take some getting used to, but looks scarily clever (or at least, complicated to implement in the first place).
