When trying to import the last couple of blog posts into Medium, I discovered that Medium couldn't parse the posts since 10 Centuries went to version 5. Instead I wrote a new, single post that summarized the last couple, since they are part of the same thought process.
I noticed when I created this post that Medium is now actively encouraging writers to put their stories behind their paywall, which is a $5/mo subscription. Even without a subscription, you can typically read 3 stories for free per month. You can read a lot more than that by using an Incognito browser window, so it's not that strong of a paywall.
Aside from funding the service, the subscription pays writers who "earn money when subscribing members read or applaud your work." Also, Medium "may" promote these "behind the paywall" posts, so you may get more readers.
This is a lot like what's going on with podcasting right now, specifically all the attempts to create "networks" and "exclusivity." For example, Gimlet Media and Anchor were purchased by Spotify, and then just today, something called Luminary is attempting to do the same thing Medium is doing with written content.
As Adam Curry has said numerous times, and experienced when he was running Podshow/Mevio, you can't monetize the network. This lead to him and John C. Dvorak pioneering the value for value model with No Agenda, which has been going strong for 11 years funded solely through listener support.
Personally, I don't write blog posts for the money. I'm not sure I want to feed efforts that are ultimately doomed to failure, either, whether it's content or my eyeballs.
