Yeah, I think people may be overthinking this, although there's something to be said for "two great tastes that taste great together". It's kind of silly, but I actually wrote a "git dropbox" command to just stuff a bare repo of what I'm doing in my Dropbox so I don't have to think about it... and I kind of like it. Maybe it's overkill, but if I only have to type one command, it's easy enough I won't think about it :-) (https://github.com/agnoster/git-dropbox/ for what it's worth)

Agreed it's a dangerous idea for collaboration, unless you are the only one pushing to it and everyone else just pulls. That could work as a simple way to make your git repo pull-accessible to others without using a separate service or server (assuming you both have Dropbox already, of course).
