You know that once a user script is installed in chrome you can edit the script.js file in the extension's directory on the fly. It's a little more work than simply putting a file in ~/.js but it doesn't require a HTTP server to function.
True, and this is why I love dotjs. Thanks for making it!
Maybe a good followup project would be to use some of the dotjs code to help make a filesystem-based GreaseMonkey system for Chrome, which would be just as easy to manage as dotjs scripts are.
Unless you don't use Firefox and you tend to have a lot of dot files that you hack around with in your home directory. Then it starts to seem pretty awesome.
Google Chrome on OS X has no such filesystem-based model for managing scripts.
