The reason twitter threads work is because it forces writers to be explicit in how they articulate their demonstrations.
No matter how long the thread, it's easy to follow, easy to scan beforehand.
When I open a medium link, there is a high chance ( > 50%) it will be full of uninteresting filler, just to make the point look important.
The only reason I would follow a link to a blog on a non technical topic, is if the author had already built a brand with me, in my brain.
For example by writing good twitter threads.
