The vdo.ninja video conference is for people who are contributing to the livestream, for example by giving a demo. There are limited numbers. For people who just want to watch and ask questions should join via YouTube, and use the live chat feature for questions.
I think the best approach for the live stream is to treat it more like a podcast with rotating guests than a live recording of a big multi-party Zoom. It’s hard for viewers to track conversations with many participants, and we should reflect on TiddlyWiki’s philosophy on optimising for reuse, and perhaps strive to get the right balance between fun in the moment and making something that will be interesting for viewers in the future.
The lag issue was because due to an error on my part I wasn’t present as director in the video call, and so Simon couldn’t hear me except by playing the YouTube stream, which necessarily has a lag from the live experience in the chat room. That’s why participants in the video chat need to mute the YouTube stream, and just rely on the video chat.
