I have 15k karma (!) and I guess I spend more than an hour a day reading stuff around here.

But I think the time doesn't matter at all, as a large part of the karma is just a few links that got popular. The rest is having frequented the site for a very, very long time :)

EDIT: and of course, I don't think internet points do much good, I would not object to hiding it completely.
