I've found myself engrossed in studying the formal language/grammar theory lately. Yet, I can't solve every problem I stumble upon along the way. From my experience, StackExchange Linguistics users are not keen on such questions as my CFG-related posts get downvotes and votes-to-close.
I understand that the completely formal Chomsky-style approach is pretty much rudimentary at this point, yet those problems are still a neat puzzle which historically gave rise to some mathematical structures used by linguists.
What is the reason behind such attitude? Should I consider any other StackExchange site when I want to ask a question of such sort?
