Off topic, but I noticed in your post you said: > but I liked the idea of keeping an “engineering notebook” as I work. I've created a site Labradoc (<http://www.labradoc.com/> http://www.labradoc.com/>) that is a low friction way to keep an engineering notebook (or as I call it--a project log). For me it makes a huge difference in being able to keep track of multiple side projects. You might like to try it out. Also, thanks for the pointer to the Javascript Markdown parser "Showdown"--I've been wanting to get a Markdown live-preview working for Labradoc and that seems like it could do the job. :)
