Hello,
I discovered a nifty game for any wiki, which is "wiki speedrunning". Where one measures the time it takes to get from page A to page B.
This video has a small blurb about it, and is how I found it by chance, when searching for mediawiki related talks on youtube.

I thought it neat, and wanted to share with the community at large.
