(draft)
We have many places related to MediaWiki and Wikimedia tech presentations.
* Check the current situation and content of each pages.
* Potentially check "What links here" for each page to understand which pages are "how popular" - might influence which page(s) to keep but also consider the specific scope that each of the sites (mw.org as dev audience, meta as Wikimedia-wide audience, Commons as a free media storage place) have.
* Come up with a plan how to reduce the number of places (e.g. merging/moving some content; set up a page redirect when killing a page)
* After having received feedback on/a review of that plan, proceed with it.
