I personally have been using git more and more for my note taking. I use RStudio and RMarkdown for my notes and it has been great and easily spread to all my personal devices.
Hmm, that's an interesting solution. You could always combine this with a private github repo and get easy-to-browse note-taking. It does seem like having to manually sync would be annoying though, is it really better than solutions like GDocs?
I use a combination of Sparkleshare, Emacs, Markdown, and an emacs mode named Deft to accomplish this. Deft autosaves my notes as I write them, and then Sparkleshare automatically syncs changes with the git server. It's pretty nifty.
