I don't think anyone will try another guy's work when it comes to blog generation.
Making a static site generator is the new babytask programming project and everyone come up with his/her own solution that's really specific.

All of them are light and simple, which is cool and interresting to look at, just like the blog itself.
That is what make personnal websites cool: even their creation comes is personnal!

And just to add up to it, here is mine, which is based on make(1) and some shell scripts (for index and RSS generation).
