If you'd like to share what you're doing via HTML, you can push the gh-pages branch (like I've done [here](https://github.com/heike/stat590f/tree/gh-pages/gadfly/carson-knitr) which you can view [here](http://heike.github.io/stat590f/gadfly/carson-knitr/)). I'm happy to help anybody that isn't sure how to do it.
