On the other hand, GAE looks like a great fit for a static site built with Jekyll, like a personal blog. In fact I'm planning to migrate my site over today. Almost any personal site will be free to host. Even though I would only be paying a few dollars with S3, I see no reason not to give app engine a shot.
One thing I worry about is the reported downtime. I'm not sure whether or not that will affect a static site.
