Twitter was never designed for back and forth communication. It was intended for people to broadcast their current thoughts (in 140 chars or less) to the world, and expect nothing back. It is only recently that threads, and DMs have been retro-fitted to the platform. But these have never felt to me, like native parts of the platform. And the styling and way in which the feed works doesn't seem to encourage debate as much as it simple encourages isolated "soundbites". I think there could be an interest market-gap for an experimental social network that does encourage active dialogue. I think the key part to reform would be the feed. Maybe instead of seeing the top level post as you scroll, you scroll past a tag cloud? Or an AI generate summary of the thread so far. Or the 3 latest comments are shown rather than the first one (so it would be more like walking past a group conversation and deciding if at that moment it was worth joining). That last idea could be interesting to explore.
