I never personally used Bing much (but memes have told me the same about its search quality). I will take into consideration for the next execution.

I have been also mildly pissed at Youtube results and given how permeated it is into a 'learner's' life, I have been thinking about Youtube too. But in that case I'll have to take more usability into account to allow for right-click>add_to_blacklist kind of thing since there are so many low-quality ad-loaded channels.
