I have been a member of Medium for a while now. Initially because it had some interesting articles but then it soon became obvious that it can, theoretically, be a nice little earner. I have been reticent until now because I previously tried out some other sites and the pay was awful compared to normal freelancing for magazines.
Medium seems different and I am completely aware that this sounds like some kind of sponsored post. It isn't though, I promise, and can prove it in three ways. One - I don't think Medium even has an affiliate program. Two - I have had millions of quite well paid offers to host a sponsored post on my websites (mostly gambling) and have always said no. The final and most convincing is that I have never read a sponsored post that said fuck.
The main issue is that I can never think of anything to write that would match what they seem to publish most. My expertise is basically writing and science fiction. There are a million posts already about writing and even writing for Medium and how to be more productive when writing for Medium and so on.
So my plan is to write a wide variety of things and see what sticks. If it starts to make a bit of cash then I will devote more time to it. I am currently writing a novel and working a full time writing job, so time is of the essence and I occasionally might want to not be in front of a laptop.
I will see how things go and will mention how it pans out when something has actually panned out. Fingers crossed.
