I suppose as a Jekyll/Github Pages user I've grown used to the levels of redundancy afforded by using the platform, and it's pretty neat for my development process to be so transparent (if anybody is bothered to look!)
If you're using Github and have a good number of followers, you also get a bit of syndication for free in the form of your commits showing up on your followers' timelines.
The only downside I've found is that I tend to have multiple drafts, on multiple clones of my blog repository across multiple machines, and I tend to lose stuff if I don't finish writing and publish in a timely manner!
