Looking over the Review section on Stack Overflow I noticed this answer; it's got 8 upvotes (mine included) and no downvotes. Why would such an answer be considered low quality? Looking over the list, there's another answer with 3 upvotes and 2 accepted answers down the list.
How exactly do you determine that an answer is low quality? I don't think answers with a lot of upvotes belong on that list. The same goes for accepted answers with more than 1 or 2 upvotes.
