I've been using a Firefox extension instead that has fairly good filters by default, because I kept getting crap results when looking at technical questions (ie. landing on over-simplified examples without details instead of official documentation).
They publish some subscription lists of things blocked that you can chose from: splogs of GitHub/Stack overflow, Pinterest... And then you can add custom blocks directly from your results list (Quora...). It can be a nice point to start with to use their filter even out of the extension imo.
