Behind every confluence, there is a fast and efficient, well organized and easy to use, "old wiki" the devops team still relies on that runs on an old tower workstation that predates the last four mergers and has no known asset tag.
The "old wiki" will teach you the builds, the kickstarts, the datacenter layout...it will show you the rack that leads to narnia....it will show you truths about yourself. The "old wiki" knows when and how you will die. It holds the greybeards forbidden ipmi scripts. The "old wiki" has no screen shots, no jira links. In the old wiki, the scrum master holds no power. The kanban but a distant billboard on the horizon.
