I'm not anywhere near an expert with git, but I'm proficient enough to use it effectively with my normal workflow. I like git, but admittedly the bar was set really low by subversion.

This article raises some valid points, though. One that resonates most with me is that git exposes its entire model. I really wish there was a git-lite that just had the few basic commands that junior developers can grok and not fuck up so I wouldn't have to waste my time explaining the same stuff for the umpteenth time.
