I feel that chemistry suffers in this regard for being the 'central science', bridging the disciplines of physics and biology. I'm a (novice) computational chemist looking at enzymatic catalysis and potential inorganic and heterogeneous cognates, so I'm in this weird borderland between quantum physics, chemistry, biology, condensed matter and computer science. Jack of all trades, master of none. I've many times started writing a physics-oriented question here only to give up on it, knowing that the chemical context will probably see it shot down.
Chemistry is like an octopus, with a tentacle in every faculty. A lot of chemists work on the tentacles, where they can easily get thrown into a 'redirect loop' of 'that's really a physics question' ↔ 'that's really a chemistry question' and the like.
This may be why we have journals like Phys. Chem. Chem. Phys....
As it stands, I'm a bit concerned that when chem.se reaches beta, it will stagnate as users jump to more specific sites for answers to their specific queries. Chemistry is a vast topic.
