That's how social media was invented. I remember when computers were things that only geeks and nerds were into. And then Neverending September happened, and suddenly normies were everywhere on the internet. We create something new to congregate, and they just invite themselves in after we make it popular. MySpace, Facebook, Reddit...even IRC and Geocities were taken over by them. We eventually took back Usenet at least, but only because it stopped being free for most people.
