Are we lonely if we are on HN?
On HN we are normally not even "online friends" with specific other users. The users are identifiable just as some little grey nickname. Who even is this "GalenErso" guy? Or "cubefox"? What are they up to? We might as well all post anonymously, the outcome would basically be the same.
That's not a natural way to interact, no wonder the brain breaks a little if it does not much else.
But we indeed do need more than this for a fulfilling life. Lonelinese could as well be temporary and one could feel less alone in different ways.
