Confluence at my last job, it was a mess. If folks don't make an effort to keep documentation up to date & organized I doubt the tool used matters much. Finally find the stage db fqdn for that one app, but turns out it was moved twice in the year since the documentation was updated? Good times!
I remember working though this with my dad when I was little, very well put together. That same copy now sits on my shelf as a reminder of where it all started for me. Still have thar ol Vic & play around on it every now and then. We've sure come a long way
