> The only way to prevent your tweets from being recommended to random people is to lock your account, and that makes it pointless to reply to people who don't follow you or to like their tweets because they don't see anything you do.
Isn't the same true of hackernews though?
What do you mean? HN doesn't have a social graph. It's an entirely different beast as far as I'm concerned.
Hacker News and X/Twitter don't have nothing at all in common. For example, both of them use HTML.
HN isn't a bunch of disconnected communities that sometimes overlap due to algorithmic feeds. It's one community with one front-page.
