@jasper why not both? I find good git comments invaluable for solving issues, discovering techniques and other code exploration.
@mrb _maybe_ if it is a big community project, it matters. But if you're just starting, just make as good a comment as you can do in a pinch..
I don't think people doing their own software project should feel like they might be doing git wrong, when for the actual software it produces,(assuming documentation is good enough no-one goes throw the history to figure it out..) it 99% of the time, doesn't matter a damn.
