If you don't see contempt in the author's evaluation of other people's behavior, you're either not looking, or not a great judge of it.
> I'd challenge you to entertain the idea that this post has some good advice, and follow some of it. I have no data, but I expect you'll be happier as a result.
Personally, I don't fit any of the implied criteria for "terminal onlineness," so your challenge isn't possible. You don't merely lack data, you lack a valid reason for assuming this advice applies to me or any other person whose habits you know nothing about. I recommend you entertain the idea that neither righteousness in your conviction nor confidence in your words transform your assumptions and personal experiences into broadly applicable maxims.
Even if this advice addresses problems you, personally, struggle with, that's not necessarily true for everybody. I know brilliant, happy, well-adjusted people, like my wife, who engage in behavior this author deems undesirable. It's just not that cut and dried. Perhaps the author's conclusions suffer from sampling bias? Regardless, I will still skip the rest of their blog entries.
