HN is the vaping to the cigarette smoking that is burning time on Reddit, for me anyway. "It's still got a lot of smart people posting thought-provoking content, and content relevant to my career, it's ok to spend time here", I console myself with.
Unfortunately I'm doing the equivalent of taking a drag from a cigarette followed by a puff of a vape now, having had a severe relapse on Reddit usage, despite internally despising the site and most of everything on it.
