What's the difference between Ponerpics and Derpi, Twibooru, and Ponybooru?

That's some very interesting phrasing there.

I read a conversation about different generations being in different internet meme cultures earlier today, and that got me wondering. How far back do you go on the internet?

Do you remember being happy when the next episode of the Madness Combat, or earlier stick figure fight animations came out on newgrounds? Do you remember AlbinoBlackSheep memes? You're The Man Now, Dog? Azumanga Diaoh?

When did you culturally embed yourself in the internet, and how much of the internet over the years did you personally experience? I'm slowly thinking that either the type of one's experiences shapes their thought processes, or that certain cognition trends might be attracted to certain types of entertainment and ways of engaging with the culture around them. I don't know enough yet to guess.

I remember ALL of those things, god help me. The Demented Cartoon Movie (was that the name?) was fantastic for something made in early flash.

I remember when it was called ARPANET. I remember when it was a secret cool kidz club for STEM majors and a handful of .mil types, when your university probably was on a regional network like BITNET and any email going outside of it would have to go to a gateway, possibly in a carton of tapes in the trunk of some grad student's car. I remember dialup bulletin boards. I remember email lists. I remember before the Dubya Dubya Dubya. I remember Usenet before the September that Never Ended. I remember dialup. I remember the Internet before the over-the-top japes from places like Pigdog all came true. I remember the Internet before it became a PC hugbox with everything censored everywhere and people trying to dox you and make you unemployable for laughing at the wrong joke. Call me Pepperidge Farms because I remember. And yes, zeeky boogy doog (kaboom!).

Here's the difference:
After being AFK since mid-October, I have the following notification counts:
Derpibooru: 329
Ponybooru: 17
Ponerpics: 4
