i keep cable for only a couple of reasons:
the kids: no i dont leave the tv on all afternoon as their babysitter, but some of its education or fun for them, and i think its ok in moderation as long as we do other things, and we do.
me: food tv. i havent watched as much as i used to, but if i want to relax i like a fair amount of the programming enough to sit back and learn soemthing, i watch comedy central sometimes too, and occassionally discovery/history/tlc.
i dont watch tv like i used to at all, i used to watch a couple hours a day at the very least, now its more like...an hour at most unless ive got something in from netflix.
