No offence, but you are arguing on HN, Reddit, Chan boards, /. now. Where is the difference? I did similarly but keep getting sucked into these communities simply because I'm alone in my head a lot of the time.
For now I don't see talking on hacker news as stressful, but I definitely will stop using this site if it becomes so.
Better than not!
Yes, it's still just wasting time away but it can be somewhat more mentally stimulating than FB drama.
