Just deployed it for an internal work blog (just happened to see this particular post at the right time), and I love new projects so I'll use it for awhile and see what I see.
Obviously it'd be "nice" to have some better contributor management, and instead of forcing me to manipulate the URL to do stuff it'd be "nice" to just click buttons, but frankly I don't care much about any of that.
Real feature request: Language specific syntax highlighting for the code bits. I'd like my snippets to come with highlighting as I explain stuff. JavaScript, Python, C, HTML to start, if you have to pick some languages. :)
Also I notice at the bottom of your blog an rrs and atom feed set of links. any plans on implementing that globally?
