@pino look, I remember fedi when it was a few tiny instances of shitposting diehards. It was great.
But instead of complaining about all the new people, I just have an alt where I only follow and allow follows from my shitposting diehard besties. And so I have my cake and can eat it too — I have my small shitposting fedi of old, and I have the vibrant and populous fedi of today.
There is no algo that forces you to interact with anyone new. You can make your timeline small and cozy. 🤷♀️
