I dont think meesterdude was implying DodgerCMS shouldn't exist. And I think the question of if it could support GH Pages is not a bad one, in fact I would rather host for free on GH than Amazon as well.
Q: Why did you make this? A: I wanted to see if it was feasible to use S3 as a CMS, and I like working on projects like this for fun.
So the author wasn't trying to create a static site CMS (there are LOTS of those already), but something different and maybe simpler.
