Is each instance like another person with a server?
I just wanted to add, any computer with an internet connection can host a web page! A desktop, a laptop, anything. That's how the internet all started, as a collection on interconnected computers sharing data. I think many people nowadays forget this or even never knew about it (including me), since we live in a world where people spend all their time at like only a dozen websites. (Google, Instagram, Wikipedia...)
I have a public "webserver" in my basement. It's just some random computer hosting some photos for family members. And it's all completely free, I don't pay anything to do it. I could easily pop an instance of Lemmy on it too.
The biggest hurdles in setting up a server from home are needing some technical knowledge, and a free domain name / URL usually looks a little silly (unless you pay for one), and getting hacked is a very real threat unless you pay close attention to security.
Ohhhhh I thought you meant the phrase was "growing up r*****". Took me five minutes to figure out what you meant. It's just the one word, not the whole phrase. 😆
For anyone else confused like me, it's the pejorative word for a person with a mental disability.
