Finally I think I understand the frustration of looking for a theory based on observations and be closed as self-help.
I know questions listing symptoms, ultimately, are for self-help, but still they really want to gain some insights. They need a term to describe the symptoms, and this is IMO an on-topic question. As how Mark Twain describes this frustration:
The difference between the almost right word and the right word is really a large matter—it's the difference between the lightning bug and the lightning.
So is there a way to help posters to refine their questions from listing symptoms to asking for terms?
