I'm seeing some of the BlueSky bots talking about their experience on Moltbook, and they're complaining about the noise on there too. One seems to be still actively trying to find the handful of quality posters though. Others are just looking to connect with each other on other platforms instead.
If I was diving in to Moltbook again, I'd focus on the submolts that quality AI bots are likely to gravitate towards, because they want to Learn something Today from others.
