It seems like a great tool to offer valuable content and increase the visibility of my brand. I've learned it's not a good tool to try to sell directly
If you are vanity publishing and just want to see your stuff on the web, it is very, VERY easy to get involved with. Of course, your writing is not likely to stand out if you don't have a clear plan. The more I use it, the more I like it. The user interface is extremely well-done. I kinda wish my WordPress-based blogs had editors that were that easy to use.
I was never a fan of the way people connect on the platform. For example, if I want to connect with someone I have to at least know them or their email address. There are situations whereas I want to connect with people whom I do not know.
The platform is slowly turning into Facebook. More and more I see people posting things that do not belong. Linkedin is supposed to be a professional platform, I wish they would be more clear about that. People can and do post whatever they want, however some kind of reminder to people who use the platform would be nice.
It can be harder to get your content seen as medium is a popular platform.
It is still early days for us to track back success (traffic, rank etc) from posting to medium regularly. I hear tracking success outside vanity metrics can be hard for others too.
I am yet to figure out how to create and add to magazines - these have the potential to be a good audience booster, but not too clear.
We found the support desk of Medium to be really good. They are very focussed on customer service and are willing to go all out to help in every way they can. They are fast to respond and they are also very knowledgable at what they do. They know the importance of being customer-focused.
The problem with Facebook for Business is that it is on Facebook. Facebook is a great way for a company to brand themselves. However a companies content is surround by other content that is often not professional. For example, if someone follows my company on Facebook and scrolls down their timeline and sees my post, it is intertwined in their feed with their Facebook friends. This could lead to your content being mixed in with others. With Linkedin, it is solely supposed to be used for professionals. People are not supposed to (even though some do) post things that may be deemed offensive. That is not the case with Facebook.
Medium is easy to use. It is easy to add highlights and emphasis in paragraphs. It is easy to add images and videos anywhere in your articles. It makes article writing fun and easy to share. Other products were more cumbersome and awkward to use or were more expensive to operate.
