Nope your right, just a lot of nerds adopted early, admittedly I am one lol. Start curating your feed and you’ll get the hang of it, and there’s a ton of other stuff here too. I’ve found a bit of everything, not as much as reddit but we’re growing. Hell if you like pop music or Taylor swift I’ve started communities for them
Remember the first forums on the internet were about Star Trek so it makes sense that it’s one of the biggest lol
