Jekyll is great, people should use it, but I wish there was more progress beyond Jekyll.
The thing that kind of blows about Jekyll is you kind of need the local Jekyll environment to build your site. I kind of am starting to get to a point where I want to be able to have some hybrid of a web interface and local dev. Something like using Github's distraction free writing to create the pages, then be able to publish without the local setup.
I guess I should just put a jekyll server in the cloud somewhere...
