Interesting that you feel older demographics
degrade a platform. For me, it’s the opposite:
I am really starting to appreciate hobby forums
that are dominated by people a couple of decades
older than myself.
Yeah, it's funny. Older demographics "ruin" some platforms and really excel at others.This is all 100% subjective, but I think many people would agree that older demographics are.... not always much fun on "general purpose" social networking platforms like Facebook.
Leaving Facebook's substantial ethical concerns aside for a moment, Facebook and Instagram stopped being fun real fast once everybody's parents and aunts and uncles showed up. It's simply too easy for Uncle Bob to repost anti-vax stuff or whatever he's into, and most people would prefer to keep some of the fun/exciting parts of their lives private from their families.
But, like you, I've gotten into some hobbies where the older folks have just a freaking amazing online presence - just super generous and talented people; absolute superstars of the community.
