I think the problem is that traditional platforms are too much for most people. They are confusing and odd in many ways. And they put this heavy expectation on the writer to come up with a long form post.
The magic of Tumblr is that it gives you a hall pass to share short form posts or whatever you care about. And it does so with grace.
