I’m a bit biased, but I think 2022 will be the year of Y.js.

What we’ve done or set up for the next year:

* The Y-Collective to fund more and more related projects, like slate-yjs: https://opencollective.com/y-collective

* The Hocuspocus backend you've discovered, which will become public in April or so

* A cloud offering we’re bootstrapping to hopefully get even more money into the ecosystem

* Y.js core support for the Tiptap editor (900k downloads/month), with a lot more advanced features coming next year

* More and more frontend libraries, like SyncedStore which was on the frontpage a few days ago: https://syncedstore.org/docs/

* The Y.js Rust port: https://github.com/yjs/y-crdt

Exciting times!
