Wikipedia has long been suffering from its rather raw “wiki markup” editing experience. The reason is that the underlying software is stuck in the mud and any progress is slow and painful. Right now there is some excitement over progress on the “visual editor” of Mediawiki. As you can see in the video below the look and feel is 2016, while the functionality is still 1999. How we will catch-up with Google Docs or Medium or any reasonable editing experience this way remains a mystery to me.
