Yes, itโs useful. I believe Iโve seen a similar feature on Discord. The first time I saw it, I didnโt fully understand how it worked, but after looking into it, it made sense. I often check the profiles of people who appear, and I recognize many of them because they use the same avatar they have on Nostr. I think streamers would find this useful. Some may choose to interact with a viewer when they enter the room, and viewers might also enjoy seeing their username or avatar appear on screen, which can encourage interaction. A simple list of viewers currently watching the stream, showing their avatars, would be a good approach.
