They have places to talk about solutions where only people who already solved the question can see them - it's just that they close the discussions relatively quickly - 100 comments or some time limit? And you can't really discuss solutions on their regular forum, because that's likely a (deletable) spoiler. So to openly discuss & share, you really have to go elsewhere.
