It is not. It is not personalized based on your social circle or activity.

HN (and Reddit) are not social media, they are forums. Social media are platforms where the main purpose is to socialise. Forums are platforms where the main purpose is to discuss the topic of any given thread. Just because you can talk to someone, doesn't make it social media. I will die on this hill.

Barely.

It's like saying "don't do drugs" (thinking of heroin, meth, coke and that sort) and someone else says "caffeine is a drug too".
