I think projects could improve by moving more of their regular workflow to invite-only mediums-- private repositories, issue trackers, etc. If someone wants to complain about your project then they can do it on their own forum, they don't get to use the projects tools as a platform to crap on the project and deprive the contributors of their freedom to ignore the noise.

Yessss!!! Or, in other words: Stop to make everything social media, stop making 'like' buttons your god, and get real again.

That would be sooooo helpful. For many parts of life.

You won't loose so much imho. It's a lot overhyped. Sure you lose all the people who are basically there for the social media factor. Well... I see no problem with that. Their perceived worth is much much higher than their real one. Social media is all about a big show. Not about actually delivering actual value.

Btw, in some regards, the private mailing list is a lot more 'open' than proprietary cloud services instead (i.e. discord).
