I write a tech blog on Gemini ( https://geminiprotocol.net/) , and read other people’s blogs from the Antenna aggregator on that network . IRC is still quite active for some topics, again on the tech theme libera.chat is the place to go now.

Sorry for the delay, but the answer was long enough that I turned it into a blog post instead. Feel free to try it out.
