In my brief experience with Twitter, it felt suffocating. Every recommended tweet didn't see me as a person to share thoughts with but as some sort of prey, like they only wanted me for my attention, formulating tweets with open-ended questions and clickbait to bait me into engaging with them.
On Tumblr, it's just people's blogs. I follow a guy who takes photos of birds. No sweating. No engagement metrics. Just cool birds. Check it out https://www.tumblr.com/doingitfortheexposure
It's relaxing.
I don't think Twitter users would get used to the peace of mind that Tumblr can offer them.
In fact when I checked Bluesky, some new Brazilian users were talking about how there was no "trending topics" section in Bluesky. A part of Twitter's interface that I personally tried very hard to avoid looking at.
