Can git help me?

Sometimes I work on creating my own project management system. More than once I have been thinking about making it into a github or sourceforge project hoping that soemone will find it interesting enough to join in on developing.

I still think it is too much of a specialized project and because of this I have decided to continue the work myself so I can streamline it the way I want it for our company.

This means I need to try new features or another approach for a certain problem. And sometimes it works as expected but sometimes I have been reverting to my previously backed up file. (I.e. copying from another folder.) I have used bazaar in the past but decided I would take a look at git since I have heard so much good thingds about it.
