I'd never heard of it before. So I read the Wikipedia page on it.

From that, I think the main problem is defining AAE (or Ebonics which appears to be a synonym) as a different language. AAE is probably more understandable to the average English speaker than the dialect of NE England [0].

So, to answer your question: I think that the term Ebonics didn't really work out, but otherwise it's going OK. There are multiple different dialects of English, of which AAE (Ebonics) is one, and they all use different words, not all of those words are in the dictionary or used in the manner that the OP is talking about, and they are all English.

How do you think it worked out?
