I wouldn't presume the problem is delving into a computer.

I would assume the problem is more along the lines of; treating it as a substitute to talking to friends/family. Only responding in short bursts or assuming a "like" is enough to sate your need for other human connections.

Reddit/HN/fora are _great_ at connecting you to communities across the globe that have a shared interest. You don't talk to your sister/girlfriend/mother via hackernews, therefore it doesn't "replace" actual discussion with them.
