I am attempting to cover all the various lightweight markup languages here:
http://www.subspacefield.org/~travis/static_blog_generators.html
As you can see, it started with "how can I make a secure blog" - i.e. one that generates static HTML, and I found myself ensnared in markup languages, templating systems, etc.
Update
I refocused only on LWMLs with python implementations, and theyre here:
http://www.subspacefield.org/~travis/python_lightweight_markup_languages.html
So far I've tried markdown and ReST, and I like the latter better for anything but
HTML snippets embedded in other pages. Tables, cross refs, indirect links, etc...
