Yeah, it can start some interesting conversations too - I don't care personally and tend to go with whatever autoformat in the editor uses. My view is that formatting code shouldn't be a human's job, adding linebreaks on long lines, spacing things out to exactly line up, etc is just a waste of my time.

That's the computer's job - it should do it based on human readability rules though, clang-format is probably the best example of these rules applied, it uses a TeX-style formatting engine for code.
