Still has a lot of the same underlying issues discord has. It’s not indexable being the biggest. The reality is that services like stack overflow or an issue tracker like bugzilla, or your local git services issues section or discussion section, hell even something like discourse or even mailing lists, just work better. If someone made an im service that could be indexed by search engines and the like, now we’d be talking. Opensorce design and discussion doesn’t really benefit that much from closed ecosystems and end to end encryption in most cases.

I guess though at least with matrix someone could make a service that acts as a client and indexes content from a list of channels or something…

Discord, matrix, slack and telegram are where documentation goes to die in the current state of things though.
