So it's private and invite only by default. There is no element of "public" and the focus is on real connections with people you know rather than people you've never met in person. There's also no notifications or "is typing". The goal is really not to try emulate existing chat or bombard you with the need for immediate replies. It's a lot more focused on how most of our lives and mine personally operates now which is with less reaction and more laid back. Group sizes are also capped at 20.

no is-typing notifications is a killer feature. sold.
