I just use emacs + org mode -> org-publish to generate my site [1] from org-mode with some customizations; it's been the most flexible and fun way to build a site I've had across all my attempts so far, particularly given that I can go meta and also publish the htmlized raw org files at the same time [2].
I'm a vim user, but org mode is one of the things that I really like the sound of from emacs.
For vim, I use vimwiki[0] in (github flavour) markdown[1] mode, and also publish the entire site to HTML. I really just use it for notes, rather than an entire website, but still, one could.
