The most requested feature, to allow a file or folder to be ignored by Dropbox sync without using selective sync is finally in beta.
The community requested a .dropboxignore file but they chose another solution which I’m sure is reasonable for making the feature more user friendly to non-devs.
This will be immensely helpful for node_modules or build target directories.
Who needs a VCS when you could just use Dropbox?
Why use Dropbox if you could just use FTP + SVN/CVS? [1]
I did exactly that: https://github.com/mickael-kerjean/filestash
As a side effect, it even supports .gitignore!
