Wordcorr helps you compare different speech varieties. People often want to know if these are "languages" or "dialects." But it makes better sense to think about that distinction after we have done the analysis, rather than making it the starting point.
Caution:
So when the ordinary speech of two social groups is different enough to notice, we can say they speak different speech varieties. That's a usefully neutral term -- we can use it without having to argue about whether the varieties should be called separate languages or dialects. Later, we should have enough information to state the ways in which they differ, and how each got to be the way it is. At that point both politics and inherent intelligibility can reasonably come into the picture.
Wordcorr comes in at the stage of identifying the systematic, regular differences among speech varieties.
