As you probably already noticed Medium has just gifted itself with a new logo, again.
The last one did not last two years, and for how much I did like the style I never quite understood the design process behind it. The today one makes much more sense to me as it fits in a “reading” scenario and it follows some kind of trend (that we can see in Italian magazines too) with bold high contrast serif typography. I can see some sort of “authority” that was gone with the previous one, but not without modernity and playfulness.
This is the background where Medium lives, as of august 2017. Given the monogram and wordmark change I think we will soon see changes in how they manage typography all-around.
