I put in effort where it's worth it. Version control doesn't even come close to hitting the top of that list.
On the other hand, I can tell you we have almost 10x more downloads than we have svn commits ;-)
To commit any changes, you type in:
git commit -a -m "thing that I changed"
git checkout -b newbranch
git commit -a -m "changes made on branch" git checkout master
git merge newbranch
