For the most part, it really doesn't matter which version control system you use. Think about it.. for most open source or even commercial projects, you have a small number of developers that are active on the project. Usually in the single digits. The level of sophistication required of the version control system isn't pretty high - checkout/checkin/comment/etc. It isn't until you have a lot more developers, a very complex project, or some other thing. Using CVS, Subversion, GIT, rcs, or even SCCS will work fine for most projects.

GIT is just the revision control system flavor of the week for primarily the Linux kernel developers. If you want to use it, do so. If not, don't worry about it. Use what feels comfortable to you.

hope this helps,
