No Shit. That sort of happens when you're making insanely stupid decisions. Banning porn gets pointed to a lot but even after that it makes no sense.
They never do any advertising. Ever. Every other social media site will but I've never seen an ad for tumblr in my life except *when I was on tumblr itself.
They don't have anything unique that wasn't made by the users. All trends and methods and whatever are made by the people. Tumblr itself seemingly just sits there and does nothing.
The site hasn't been changed much in a decade. There have been a couple tweaks here and there of how things look and function but nothing new has been added. It's just aggressively keeping the status status quo but the format they're using is ancient. It feels outdated.
They don't capitalize on anything important. When Twitter started to implode, Tumblr has a huge influx of users who are escaping Musk but just sat there. All these new people jumped on and were confused but tumblr didn't even bother to release a short video or a post even welcoming people.
Yet when Twitter then added the "Buy a checkmark" thing, tumblr went "Good idea!" and added the ability to do the same thing as a bit of a laugh. There's no consistency at all on when to do something.
There isn't a single serious person working on that staff. Everyone has been running tumblr like it's some small niche site when it's one of the biggest social media sites on the planet. I don't want them to turn into reddit or something but they aren't doing anything at all.
