META: I don't really understand Area 51. If I want to access 'Stack English' I can find it quite easily. "Area 51 English" INTUITIVE?
What is trying to be achieved here?
Actually, I can see how it is not really working. It is difficult to find a good boundary between 'English for Learners' and 'English Language and Usage'. You could say 'English for Native Speakers' and 'English as a Foreign Language' but that negates some of the advantages of the internet as being a world wide communication tool.
Perhaps English Language and Usage should widen its remit and recognise that the majority of people who are interested in English are interested in either learning or teaching it.
