I had recently posted a brainteaser on the site and it was closed. I just joined the site a few days ago and I was just wondering why exactly asking such questions is not appropriate.
Is it because people would try to exploit the reputation system or something? Would it be possible to introduce such questions on the site because I think it would be a good idea.
PS: I love the concept behind Chemistry SE and I'd be happy to help out in whatever way I can around the site..
