Here is a problem I'm having. Tylershads gave a great answer to my last question. I would say it's pretty much the definitive answer, however one of the problems I know this site is having in becoming a regular site instead of Beta is that a lot of questions get one response. I've started making a habit of waiting longer to award an answer to help encourage more answers but it doesn't always help. I feel this question even though it has a great answer could have more answers given, not necessarily different with the main information but with more angles or perspectives thrown in. There seems to be more in the comments inside of this Reddit link that Tylershads links to in the comments on this answer. Now this doesn't really have to do with this specific question it's just the example that I'm using to ask how can we encourage more answers to one question? These are movies and tv shows there should be lots of opinions out there.
I think part of the problem is that a decent amount of our questions are easily answered in one to two answers. The questions that tend to get the most answers are, of course, identification questions.
The analytical questions on movies that are deeper tend to get a wider range of answers, but those movies aren't as popular. I think it's something that we can't easily fix.
