Well we can assume political discussions have a lot of psyops and people with agendas. I appreciate that many of the loudest voices/posters make it very obvious ;)

Some of the craziest niches aren’t on here (like if you clean sewers and septic tanks, DM me, you ought to do an AMA) but I have encountered people replying on mostly tech related topics on programming, linux, asklemmy, no stupid Qs where someone with niche tech knowledge could answer. My knowledge is in trains, electricity, Japanese and Japanese electric trains, you can ask me about.
