Eh, I think the parent has a point. You underline it yourself when you say “people they already know”.

The internet didn’t always involve a choice between “talk to people I know” vs “bravely/foolishly taking on the vitriol of a wild horde of angry delusional maniacs”, but now we’ve lost almost all of the space in between those extremes. People like hacker news exactly because it’s the rare place that’s still in the middle *(sometimes, on some topics, for now)

There’s a lot of people on hackernews with whom I cannot agree on a great many important things. Happily, none of them appear to be technical, so it works out fine.
