Fucking stupid. I get why they feel it's necessary, I just think they should make it optional for us to have it closed. And I know they are just trying to encourage new opinions, I guess maybe they should include an incentive like +2xp if you answer a question that doesn't have an MH yet, +3xp if you're the first opinion. So like you still get one for answering a question with MH. But you get more if they don't have it selected yet.
That way, we can choose to have our questions open or closed, and it's still an incentive for users to answer questions without MH.
I sometimes get really (and still relevant) good advice months after the question had already been asked and MH selected.
I find it counterintuitive of this site to put that much limitations on answers, when this is the whole point of this site. Lol this is literally why we joined! :x
