I think I win, or lose, depending on your point of view. Most people consider me fairly well-adjusted and successful. (Quote my aunt, to my cousin: "See, you can like geeky things and still grow up to be a productive member of society.)
Nobody says boo about someone who watches 3.86 thirty minute episodes of TV a day, or who writes 3.86 pages of email a day, by the by.
I say 4 things a day on a website and that's obsessive?
I choose what articles to comment on. There are a LOT more than 4 per day. I choose WHEN to comment on those. I don't have an RSS feed on my phone that alerts me to new stories so I can be first. I post when -I- read the RSS feed and see something worth commenting on.
That really depends, it seems reasonable that someone could comment at that rate and still make the claim if they allotted an amount of time to browse and engage on hacker news each day. Also commenting rates vary a lot between people, I may spend hours here and only make a couple of comments. Others may comment more frequently or focus on the shorter material.
Somehow that doesn't strike me as a behavior pattern of someone fully in control of his web browsing habits.
