DuckDuckGo is shit. They've probably sold out (or were never truly unbiased to begin with). I've written to them before about some of the fuckery I've seen in search results, but nothing changes.

I'm waiting for Yippy to become more user friendly and better at fetching search results. Then I'll switch. Yippy still feels like it's in beta for me, but hopefully it'll get a lot better.
