Discoverability of groups is an issue. Unless you see someone @mention one, or drill down into peoples’ profiles, there’s no way for a new user to know what groups there are.
Super excited to see this, and that there Will be improvements to groups.
I’d love to be able to export a copy pastable list of group members, to be able to write to them all or mention them by name.
Also maybe the option to allow groups to be used to start private messages to a list of users instead of in the newer group inbox. that way we could start conversations with a more granularly created list of people, and add and remove people as the message evilves.
