Gryffindor: shitpost meme blogs like "I will eat your shower curtains" or "the lead guy in Baby It's Cold Outside sounds like Morgan Freeman"

Ravenclaw: the science/nerd side of Tumblr running their cool facts blogs and also saying "in this essay I will" mostly unironically

Hufflepufs: in charge of wholesome positivity blogs and cute frog blogs

Slytherin: the ones with aesthetic fandom moodboard blogs and those rebloggers who say "op what the fuck"/"it is 2 am and too early to question my existence"/"hOW DO I ESCAPE THIS SITE"
