I've ended up going from applications like Evernote to a simple Dropbox folder with markdown files for my personal notes. For me, the main draws are easy access from terminal and using my own text editor. And of course code blocks with syntax highlighting (and LaTeX with MathJax). I haven't played around with sharing, but it's easy to render an HTML page.
