A static blogging tool for hackers. You create your posts in a GitHub Gist. Add them to your blog on Grite and it just shows up.
Other static site generators need you to generate the site, once you change the content. Here you don't need to. You create or update a gist, and you can add posts to your blog, all of it online from GitHub!
This means that you can use all the goodness of Git in your posts, you have revision history, you can fork other posts, etc. You do this all online, without cloning the repository on your machine.
This page itself is a Grite blog.
