I use talkgroup.xyz for a lot of weird things, but the original idea was to have a cool email/web forum interface for conversations with my peeps. So we all don't need to host comments on our blogs, really. In my tribe we often don't know where to post stuff. Like, this isn't a status update, and might only apply to some folks... that is what talkgroup can do.
And you are all invited. Things are chill, and everything is CC0, and changes get discussed in meta (https://talkgroup.xyz/c/meta).
