That would be fine for things like source code or documentation, but you end up with a single person who would need to merge / push things to a central location, a-la git.wiki.kernel.org. You are now taking something, that is already editable by anyone, and making it only editable by a single person.

You also have a scalability problem. Git is *VERY* memory and i/o intensive. While you basically have a cache of data that is static (the basic pages you are viewing) things like the history, edits, etc can be quite expensive to generate.

Think about a site, we'll use git.wiki.kernel.org, where it's not running on a single machine, but a cluster of machines (how many web infrastructures, including git.wiki.kernel.org run) and now you have a problem of an edit happens and commits on node3, a different conflicting edit happens on node9 and when those try to merge - you get conflicts.

Let me be clear here, I think the idea is interesting, but I think in trying to replace a full wiki it's a horrible idea, particularly since you are pushing a lot of manual work - somewhere, and trying to use git as a nosql database without some sort of locking system.

Just my $0.02 though.
