At first it was all about presenting data in an original looking way. In the end it was about pushing political ideas in your throat using a plain bar graph. It was not about sharing something interesting you found but about taking advantage of a captive audience.
Most of AITA was fanfic too - just a deeply improbable amount of twins, pregnancies, weddings, and twin pregnancies at weddings. Once I stumbled upon a megapost that was all the ones about food, though, and it was great, because nearly no one bothers to make up a drama about lasagna.
The one silver lining was it brought us the glory that was the “everything in this sub is fake” punchline story, if anyone else remembers that one.
SO. MANY. WEDDINGS.
