I listed death cult apps because that’s what most people use, and I knew anyone who didn’t use said apps would be sure to tell me. Also, I put @6538925e…571e55c3 in a different category. They’ve had “zaps” (“boosts”) for years. They also integrated Nostr a while ago. They also have video in addition to audio. For bitcoiners who only use death cult apps, I always try to push them toward fountain.
