Scott Adams said it best. Cable modems will never be as successful as phone-company services for this reason: The people who work for the cable company are the people who couldn't get jobs at the phone company.
True enough (I'd never dispute Scott Adams' wisdom in these matters) but somehow in our area the phone company manages to screw things up worse than the cable companies.
