So many of these quotes either get downvoted or have terribly rude comments about how that particular quote has terrible grammar, syntax, spelling, or punctuation. Even if that is true, commenting doesn't really do anything, and downvoting will get it removed. To me, this is not usually necessary, especially if the quote is otherwise good or inspiring. My solution is, of course, the edit button. With a few keystrokes, you (yes, you) can edit the quote to make it good!
Exactly! The edit function is there for a reason, so that we can improve other people's quotes. Also downvoting doesn't get quotes removed now, so it's kinda useless.
