In all of the Jekyll vs. X comments below, I think an important selling point of Jekyll is being missed:

It is built-in to Github Pages

This saves you the trouble of re-generating the site on your local machine and pushing it to a host.

also for organization projects we can allow anybody on the team to edit and post directly from github's web interface.

That's a great point. For collaborative blogs, using Jekyll/GH spares you from having to sync permissions between your source control and your web host. That's big part of why we used Jekyll for SeattleHacks[1].
