I have a friend who’s thinking about checking out the fediverse, and is looking for more aerospace (& maybe mechanical?) engineering-focused spaces. Do you guys have a suggested Lemmy, Piefed, or Mastodon instance/community that focuses on those topics? Maybe even a STEM community could be good enough. I know most of us are tech nerds on here, but we’re more computer focused tech nerds 😅
My only requirement is that the instance can be viewed without sign-in, as I don’t want to force them to make an account to check it out.


Good list. What I love about these specialized spaces is they’re built around shared interests rather than algorithmic engagement.
I think that’s why projects like Zeitgeist resonate with fediverse folks - we’re trying to measure genuine opinion, not engagement bait. If you can see people who care about aerospace, or science, or privacy talking directly without an algorithm reshuffling the conversation, that’s the internet as it was meant to be.
