I think it’s the loneliness then. The other thread about why we waste our time on the Internet had that as the top comment.

So you see loneliness makes us waste this part of our time probably in an futile attempt to deal with loneliness, forge a connection, having some kind of reassurance that we have a voice and maybe we matter even though we so don’t.

So this comment isn’t waste of OP’s time if OP likes to do this or wants to do this and gets gratification from it (even if doesn’t last beyond hitting the submit button). OP even mentioned that coffee thing in the similar vein.

So I think you were being snarky. Maybe inadvertently? Or just another knee-jerk comment like most of HN? :)
