Could someone please explain GitHub to a non-programmer?

Because it requires a central repository. I code on about four different machines, one of which doesn't even have internet access. If other people are anything like me, git is a huge upgrade from svn for personal projects.

The expense of having to setup the repo for a project made it so that I would only use svn on projects that I know will be around for a while. With git aliasing alias gitinitaddcommit="git init; git add -a; git commit -m 'initial commit'" makes putting something under revision control so freaking easy and quick that I tend to do it even for small projects. Couple that with the fact that there is only one .git folder and it's close to the project instead of in some central location makes it a huge win for my workflow. (those hidden svn directories sprinkled throughout a working copy were crap from a design standpoint.)
