I mean, for this topic: Understanding chemistry as a whole. This is clearly not "homework".
But then, maybe, I (being relatively new to chem.SE) am missing something? Maybe we already have a tag with similar meaning? Or maybe it has been discussed and proven unnecessary?
Upd. I didn't mean it to be about basic-chemistry or chem-101. It's more like philosophy-of-chemistry or methodology-of-chemistry. The tag wiki may go like
For questions whose answers can't be objectively evaluated as correct or incorrect, but which are still relevant to this site.
(I copied this from math.SE, they have a somewhat related tag soft-question.)
Upd. 2 And here is yet another: https://chemistry.stackexchange.com/questions/50966/how-is-chemical-knowledge-organized, marked as homework (which it is not) and closed as too broad. How chemical knowledge is organized, really? "Shut up and learn, that's how". Is this really the message we want to convey?
