As I'm in the midst of essentially making a simplified Google AppEngine CMS for use in my home page, I came across Bret Taylor's blog. It's hosted on appspot, he apparently put it together from scratch using code he'd developed elsewhere. The blog is a great example of what a nice minimalist app can look like when well executed.
Even better, he was nice enough to post explaining what he did: Experimenting with Google AppEngine. On top of that, his blog's source is also available on GitHub.
all in all, it's some nice stuff, hope I can figure out how he did everything.
