Not only did Tumblr activity collapse after the NSFW ban, but in the subjects I follow, activity seems to have settled on a niche of transwomen blogging about hobby or interest X, where their posts are mainly about being a transwoman interested in such things and not the hobby or interest itself. I understand that Tumblr has value for those transwomen wanting to express themselves and build community with others, but it has become a network relevant to only a tiny, tiny percentage of the population.

Is it possible you are in some kind of algorithm filter bubble?

No, it’s just that intellectual subjects on Tumblr always attracted a certain share of neuroatypical people, and once the majority of users left Tumblr, only the neuroatypical remained.

Tumblr has plenty of discussion about hobbies, TV shows, anime, video games, etc. If you like a certain thing, tumblr is a great way to be exposed to people discussing it, making text jokes about it, making fanart about it, etc. That has been literally unaffected by the NSFW ban in the many fandoms I follow on it.

There are people like you describe, but it doesn't dominate the platform imo. It's easy enough to get a lot out of tumblr.
