I wouldn't call you whiners, but I would say that surely you didn't join without first reading through the posts to decide whether or not you would like it here. You must have seen the acronyms then. Joining was your own choice.
So is joining any particular conversation - you might choose to avoid certain topics. Also some threads include references to concepts or information that you haven't met, using words you don't recognise. If you want to join that thread, you either look up what is unfamiliar or you work out from the context what they must mean - or lurk quietly for a while and learn a lot. There have been complaints they posters should only use words and concepts that everyone understands, and not discuss anything in any more depth than that, but I don't imagine you would go along with that?
