An open source, fast, customizable cross-platform text editor with native UI and support for plugins and language servers. I don't think there's any other software that can tick all these boxes.

What an oddly aggressive tone x) It's not "my" Zed's selling point because I don't develop or even use zed daily atm. But it's also not the selling point period, it's one of them, the others being e.g. performance, responsiveness, and low memory footprint, as well as integration with tree sitter and LSP.

Not sure what you mean by gamification and social, we're talking about collaborative editing, not posting to twitter lol

Zed's selling point is performance
