I kind of hoped this is an April Fool’s joke, but the post started a couple of days ago. 
I’m honestly disappointed because the Wiki did pick up the slack where Unreal’s blogs, documentation and forums lacked. Even some forum posts pointed to items in the Wiki. I still don’t understand why it had to be disabled before it can be fully incorporated into the documentation. There were a lot of advanced C++ subject matters that the Wiki explained very well. I hope all of that can be placed into the documentation because the Engine is a beast and these wiki posts helped a lot.
