[flerdle] So that Google doesn't link my uni page to this one, perhaps I should suggest you type my name into the venerable search engine, click the first link (at least, the first link in our part of the world), and towards the bottom of the page you can find a link to the relevant preprint. I heartily recommend the books by Gordon and Trudgill if you really want to get into the details of the empirical data, as opposed to our modelling.

Trudgill rings a very faint bell. But well done you - I enjoyed the interview.

[nights] He is one of the more notable names in dialect research, especially in the UK; it would be hard not to have heard of him at some stage if you've looked into this field much.
[rab] Thanks very much.

Ah yes. I did a study of dialect changes amongst adolescents for A Level English Language. It was good fun. Got an A and everything.

Ah, A-level English Language. How long ago it seems now ;)
