People say "ye" all the time, they just don't write it that way." We might write it "What are you doing?", but for many if us the chances are that what we actually say would be much more accurately represented by writing it as "What are ye doing?"

There are lots of examples of that kind of thing. For example, you have people look askance at spellings like "dis" and "dat" for "this" and "that" as ridiculous, and then go on to pronounce the words that way after all. (I don't mean that those kind of "dialect" spellings are a good idea, because they have tended to be used in a way that implies some kind of put down, and they have the effect of distancing readers from the actual sense of the text - but they do represent actual pronunciations far more accurately than is often recognised.)
