As a true red white & blue American I want to second mousethief on the Yankee propensity for down-culture expression. I think it's interesting because it's due to an anti-individualistic motive. Most of us see no problem in obtaining an education, but it's perceived as gauche to call attention to it.
The hideous mis-use of apostrophes made the front pages in Anchorage this Summer. Have seen no sign of it in the States. Among my co-workers is a disturbing misuse of 'myself' such as "Call myself when you get this message." It drives me up the wall (and round the bend).
