I just did some research on the rate of closed questions on this and other, similar sites. Of our most recent 50 questions, 19 have been closed. At least nine of those questions were asked by users with <50 reputation gained on this site. Based on the SE.com default sites ordering, this site is currently at about the same level as
- Christianity: 10/50 closed questions
- Audio/Video: 1/50 closed
- Travel: 6/50 closed
- Japanese: 0/50 closed
- Parenting: 2/50 closed
- QA: 1/50
I think it's fair to say this site has it much worse than other sites. Christianity is the only one that comes close, and that should almost be expected for a site on a topic which is naturally quite subjective, and is just 3 months old. The Judaism site has been around much longer, by which point they've basically sorted out what is acceptable, and they have just 3/50 closed questions.
I'm not sure what it is about our site that attracts the wrong kind of user. If you think you know, feel free to chime in with an answer. Until then, I propose that we request from the SE team that, for this site only, reputation be required before asking a question.
