I agree with everything you're saying, Aleks. It would only be worth doing if we believe that a better kind of conversation is possible - due to the long-form nature of the medium itself and the moderation that's possible. And while people should be able to discuss bad actors, I was not thinking of that kind of stuff when I proposed the idea - I was thinking of design conversations.
Examples are hard but let me give it a shot. Right now, there are some discussions I'm seeing on:
1. alternatives to kickstarter if you're interested in crowdfunding
2. critique in ttrpgs - thinking of the video on zedeck as a great example of something I'd like to see more of (https://youtu.be/J3gsHlnczJM)
What do you think?
