Tumblr genuinely is younger than most other social platforms, and more diverse. A greater proportion of its users are people of colour than on any other major platform. Women users make up a higher percentage than anywhere else bar Pinterest. Teenagers over-index dramatically. And while Pew and other research agencies don’t tend to ask about sexuality or gender identification, LGBT visibility in Tumblr fandom is very high. What looks to dim outsiders as some kind of obsession with “social justice” often just springs from people talking about themselves, their lives and the shit that happens to them.
Just one of many excellent parts in this piece by Tom Ewing (which is only a little bit about Tumblr.)
(The piece is about Marvel fandom, though that’s not apparent from this quote.)
