It's written in coffeescript and node.js instead of ruby. Jekyll is also made for blogging, for instance you have a _posts directory in Jekyll, in DocPad you have a src/documents page - this allows you to create urls like src/documents/about.html -> /about, and src/documents/projects/docpad.md -> /projects/docpad, and src/documents/posts/life.md -> /posts/life. Another great thing is that you can access the query engine inside the views, and the data associated to documents can be filled with whatever key values you want - so you can do advanced filtering/queries. The benefit is that you can extend the docpad server to do whatever you want (as it is just a node.js package) even add redirects and dynamic pages to the mix. Feel free to join me on #docpad on freenode.
