For centuries, refugees sailed the Atlantic to start new lives. Easterners pulled up stakes and went west to California. Today, however, reinvention comes less easily and second chances seem more remote. You may leave town, but your electronic shadow stays behind, as anyone who has ventured onto the Internet well knows.

It has preserved my expired site, and it may well have yours.
