Been using duckduckgo for years. At least for the type of content I’m usually searching for, mostly tech related stuff, it seems to me that it has always had great results.

I’m mostly lurking at HN, but I do like it. I find the submissions interesting and most discussions are high quality. There are some subjects that are… let’s just say not HN-friendly and any discussion ends up in the same echo chamber. But overall a thumbs up from me.
