I'd considered 'Y'all' as a substitute for 'you' (plural, and confusing at times) and 'youse' (plural, but unmelodic at best, ugly at worst). The only problem was the usage I've encountered in America - 'y'all' was used even when addressing someone in the singular. I looked over my shoulder the first few times this happened to me - in coffee shops or small bookstores, say - expecting to see someone else. standing beside me. The pedant in me wasn't keen - surely 'you' is fine for one person, 'y'all' implies more than that?
