812 Area Code gets an overlay

Some are complaining about the decision to do an "overlay" for the 812 area code, instead of splitting it geographically. With the advent of web calling by Skype and Gmail, many people already ten-digit dial. Plus, many people keep their cell phone number when they move into a different area code. I don't think this is a huge inconvenience. It would be a bigger inconvenience to force people to change their phone number.
