So the useful question is not “how many hours do you work?” but “how much energy do you put into your work?” Other useful questions that come with it are:
* How much of your daily energy do you spend increasing your total energy? Do you feel you spend enough? Do you feel you spend it on the right things?
* How much of your daily energy do you waste each day? How do you define waste? Is all that waste really unproductive or does it have some beneficial side-effects? Are those side-effects sufficient to justify spending that energy?
* Do you spend energy on things which actively hurt you?
* Has your daily energy increased or decreased in the last 6 months? year? 5 years?
Any of these questions is more worthwhile than “How many hours do you work each day?”
There's a sort of Gresham's Law of trolls: trolls are willing to use a forum with a lot of thoughtful people in it, but thoughtful people aren't willing to use a forum with a lot of trolls in it. Which means that once trolling takes hold, it tends to become the dominant culture. That had already happened to Slashdot and Digg by the time I paid attention to comment threads there, but I watched it happen to Reddit.
News.YC is, among other things, an experiment to see if this fate can be avoided. The sites's guidelines explicitly ask people not to say things they wouldn't say face to face. If someone starts being rude, other users will step in and tell them to stop. And when people seem to be deliberately trolling, we ban them ruthlessly.
