It's still the least bad way to just write something and put it on the internet in a way that looks non-awful. For people whose focus is the content, not the, uh, medium, it still makes sense.
I guess I won't really argue. The appearance is good and, if you don't want your own blog (which is still more work to setup than it should be unless you're a web designer or pay someone), I suppose Medium is a reasonable option.
