To be fair, if you don't use Twitter then you are already well removed from the target demographic that might find Mastodon useful. That said, there are a lot of really useful takes on Mastodon on various topics. Politics is probably the area where you will find the most number of takes. But in infosec, and game development at least, there's a lot of interesting info. The biggest issue with Mastodon or the fediverse rather is the lack of full text search and the cultural push back against it. I don't view the push back as negative. It's a sign that the community has strong opinions and that's a good thing. But the lack of search does make it hard to peek into a conversation around a topic which to me takes away from the experience of jumping into communities of interest.
