We're currently training some devs from another team, which were doing some development before, but it wasn't their bread-and-butter.
And yeah, commit messages are one of the bigger differences, where they just don't quite take things as seriously.
But that's due to a chicken-egg problem. They're not really well-versed in creating atomic commits, and apparently so far, they've been merging basically at random, creating a rather complex history.
And of course, they've been embedded in a team where everyone else didn't take these things as serious. So, even if they put lots of efforts into their commits, they're be much less useful when they're placed between badly separated commits.
Really makes me feel like we need to put special focus on Git for a while, to give them the tools to appreciate working in our useful commit history.
