@julian yep, this is really good. I wonder if using domain names is the right way to label the bigger bubbles. So I can look and say, "Oh, acm.org, that's the ACM. stanford.edu, that's Stanford University. hci.social, that's a community of practice for HCI professionals. fietkau.social, that's a personal site for Julian. threads.net, that's a big commercial network." With the implementation software (Mastodon, Pleroma, etc.) as a secondary bit of metadata.
