Ok, gonna try to use this instead of twitter. Sociolinguistics question: vowel shifts! This is possibly a obvious question - there are some examples where vowel shifts seem to have social causes (northern cities shift), but are there any that just look random, or a general trend to shift which doesn't have a social cause?
@impractknow There are a few over here:

There's no /fəʊˈnɛtɪks/ list yet, because there hasn't been enough interest. But if you ever get three more people who'd like to be in it, we'd be happy to add it.
