This is my go-to example of the type of hilariously terrible Quora answer that plagues the site: https://www.quora.com/How-do-I-learn-competitive-programming...

90% of that "advice" could be copy pasted onto any "how do I learn something", and the remaining two sentences related to competitive programming are so vague that he links to the wikipedia page on "Algorithms" and the wikipedia page on "Programming Language"

And that gets you 460 upvotes, far above some of the better answers at the bottom of the thread.
