Yes, as long as people would actually install it and care to use that medium at all. Like I think everyone my age (30s) would do it, but I know my parents wouldn't.

But as an easy social/community tool for a small group when you want something more than just a WhatsApp group, it's great.

The downside is that it's just chat and thus any important info being discussed can be hard to link, find, and centralize. I'm part of some organizations that handle this by having a Facebook group as a lightweight forum and landing page of the organization along with the Discord for more hangout and meet each other vibes.
