If you really want to know how people use the English language in North America, you will find one consistently reliable peer-reviewed source of information, four times a year: the journal American Speech, sponsored by the American Dialect Society and published by Duke University Press. And though it is scholarly and research based, there’s a surprising amount of information that is intelligible to anyone, even without special training in linguistics. The current editor is Thomas C. Purnell of the University of Wisconsin at Madison.
