This article glosses over what I consider to be the killer workflow of Fugitive. Specifically the ability to trace history extremely efficiently across any kind of refactoring.

The flow is: 1. :G blame to blame the current file in a locked split 2. navigate to a line, then hit o to open the commit in another split 3. search for a change of interest, then navigate to either the --- or +++ line and hit o to open the before or after version of the file in another split 4. repeat steps 1-3 as needed to drill to whatever history you need 5. ctrl-w o to kill all the splits and leave you with just the buffer of interest

whereas I'm pretty happy with git CLI for the majority of git interaction, and a graphical client like gitk for visualizing branch history, I haven't found any other history inspection technique or tool that comes close to this.
