Maybe we should start a forum for those of us to whom these things matter; (baggsy I be blackboard monitor)
I enjoy hearing regional accents, as long as I can understand them; I admit to having difficulty in Glasgow and when I used to service some equipment in the lab at Nissan I would often struggle. In the latter case, these were educated people, mostly with degrees. I also find the use of regional words fascinating: one in particular, from Yorkshire, is "while", meaning "until" e.g. "Wait while I finish" where most of us would say "wait until I finish".
