About 5 million people is good. I was on Digg as it grew and became shit. I was on reddit as it grew and then became shit. Once the active user base goes over ten or fifteen million people, things start going down hill. Advertisers and bots and mods that can’t keep up and too much outside press and governments mentioning the platform with unwanted attention.

Right now things are OK for general news and info, but not big enough for more unique communities. Like I can’t go to a community within lemmy to find another thousand+ people all about yo-yo’s, but reddit has r\throwers with over 40k subscribers so I can go this “stout guy” show me how to do a new trick.
