Where does Ask Jeeves traffic come from?

Does the name show up for other search sites

I have a newish site that is chugging along ok, building slowly.

Over the last week traffic from Ask Jeeves has just gone crazy, I am really perplexed by it. Where does it all come from? This is what the search engines sent me in the last 7 days.

I am happy about it - they seem to be good ad clickers! - but can't quite understand it.
