Mastodon never had a good amount of orginal content to explore, only very few creators produced and shared. Topics I followed were mainly infosec, programming, biking but content and interaction faded dramatically over the last 6 months. You won’t get anything back, no reach, no constructive feedback, no real life contacts. Twitter was a place to get inspired and learn new things, find OC memes, code snippets, niche insight, etc. Mastodon lately just went full anticapitalist, anti-tech, anti AI. Nothing insightful. Irrationality. Depression. Reddit is still a better place to discover and discuss things, if you find active subs covering a topic.
