I agree with you. I really like it. Worked well for me. I'm also incredibly impressed with the results. Is this a search engine grown from the ground up with its own crawler or is it using an existing dataset? If self-created this must be worth something right now

The search engine seems to have been built on top of Yahoo BOSS

Yahoo! BOSS launched on July 9, 2008: http://www.ysearchblog.com/archives/000599.html

Duck Duck Go's site says it was in development for about a year. If it was indeed built on top of BOSS, the developer must've spent 10 months doing pretty much nothing.

Ahh, ok - I was completely blown away by what looked like a 1-man creation :) Indeed, I still think its great for one person to have done this. Gonna look at Yahoo! Boss now. Thanks for this

I liked it too. Particularly the fact that it shows 4 results to start & lets you extend.
