I realize that there are similar questions, but my question is slightly different: I\'m wondering whether sharing a bare repository via a synchronized Dropbox folde
If I told you that there are cases in which Dropbox has screwed up my Git would I answer your question by contradiction? At least in my experience, this has happened more than 5 times and there are a lot of people having the same experience out there.
But nowadays I don't believe that Dropbox is really that essential with Git, really. Actually you can set remote branches (Github, Gitorious, Bitbucket) which can replace Dropbox sharing and revision history features (isn't all that about Dropbox?) and offer you even more.
