Sorry that came off as negative. It's more or less a very limited amount of time. That's one of the reasons I can't get a "regular job". My wife has an illness we haven't gotten a stable diagnosis for yet, which makes her exhausted all the time, leaving me to watch our 5 children (from teen to baby), which is a full time job in and of itself. The few times I do anything during the day have to be done in tiny windows in which the kids aren't trying to burn down the house and terrorize each other. And I've been consistently getting less sleep than I need because I try to get little amounts of job searching or entrepreneurial work done during late hours. So any time I have to dedicate to doing any of these things, including commenting on HN, is sleep-deprived and rushed.
