Stackoverflow has got its userfriendliness problems and all, but I still like that whenever I find a question that I have too, that the answer I'm looking for is probably at the top of the answers. If not, I navigate away immediately.

On the other hand, if I find a question on github, there's so much pollution and scrolling that it takes a lot of time to assess whether the answer is there at all.

Also I feel like github is being used à la Stackoverflow more and more, Q&A rather than repo, but I am against this movement!
