This is similar to this question from 2014 (and this one... which is remarkably similar...) but I'm asking how it's actually collected rather than asking for it to be fixed.
As someone who submits a lot of top answers on M&TV to questions that regularly go on the HNQ list, I'd like to know how this list of names is compiled.
Does it simply strip the username from the question and post their name in the sidebar?
If this behaved as advertised and showed top answer usernames in addition to the question usernames, what would make something a "top answer"? Simply having the most votes out of all answers? Most votes with a minimum vote count of 10? All answers with greater than 10 upvotes?
