Read HN only on Saturdays (or some other fixed day of the week). I can easily waste 2 or 3 hours a day to "keep up" with the news, this is ridiculous.

Trying to learn something truly worthwhile by reading the news is a bit like trying to learn by watching TV or trying to get rich by buying lottery tickets: sometimes it works, usually it doesn't, and even if you succeed it's not quite as edifying as doing it the right way (ex: learning useful knowledge by reading books or getting rich by starting a company).

I'd be interested to know if there's some day of the week where the stories are usually the most relevant.
