Forums typically allow much more discussion in posts, along with several types of post that Stack Exchange frowns upon - list questions and shopping lists come to mind. If we want this site to be like a forum, we can have that kind of thing.
If we want the site to be more like Stack Exchange, however, then each question should have an objectively "correct" answer, instead of multiple such answers.
Personally, I don't mind. What does everyone else think?
