I remember looking into them and not pursuing it. I don't remember the reasons. I think I'm reading about them here and in the comments. Thanks to all. Writers don't have time for that kind of platform.

As for Medium, I don't use it to make money, so that part is fine. As you said, we can say what we want, even if it is ridiculous.

The nice thing about Medium is that it has a lot users who can actually think well enough on their own to reject my more idiotic attempts to persuade them.
