I want to think I did my research. Wondering why just a handful of posts related to #FrOSCon turned up in my client, and I knew I was missing posts others mentioned, I went back to my reading.

Turns out I never subscribed to any relay services such as #FediBuzz Relay. Folllowing the instructions on https://relay.fedi.buzz is super easy. I just never did after learning how it works 🌴
