pardon my ignorance but why are people posting nitter links every time, what is wrong with original twitter urls?
Twitter is basically broken if you don't login, compare this:
https://twitter.com/andrewmccalip
https://nitter.net/andrewmccalip
In Twitter the latest tweet I see is from July, in Nitter is 22 minutes ago. Additionally in Twitter I get 3 notices/popups that I need to close.
We should discourage the use of walled-gardens for public discussion anyway. Otherwise nothing changes ever.
Do you mean closed source software? Because that would rule out Hackernews. But I agree on the principle. Maybe it's the type of discussion. I would be happier if this very exciting superconductor story was unfolding somewhere else than Twitter.
Hackernews was released as free / open source some years back. There's a community managed fork: https://github.com/arclanguage/anarki/
