But nope I think that would be pointless and would start drama on the internetz which is funny in the first place but would get annoying and therefore could all be avoided with only a best answer option...(:
I think only the people who start those hostile religious questions would use a worst answer seriously. Past that, I doubt anyone his isn't already thinking will try to think harder to avoid a worst answer. At the very est, they will rely on a selfless troll to absorb the blow.
It`s a good idea, to have the worst answer. So we would have kings and queens ( or masters) of stupidity, banality and lunatic. Maybe we could educate them more or less.
Also it could be funny from time to time, to crown the queen and the king for such. Such a person should get a laurel.wreath with an arrow downward by his/her avatar. This could happen, by a special number of worst answers.
But knowing that this site is like a high-school of inwardly troubled people who desperately fish for perks, approval and positivity instead of honesty and an advice what to do, it's very unlikely this feature will be implemented!
Worst Answer award is clearly negative, and it may only discourage people from saying anything! Right now the only "negative" thing is downvote of answers, which does absolutely nothing to you, though we still see many people crying about it and asking it to be removed!
