Writefreely alternatives

I think writefreely – nice as it is – might be too limited for a digital garden with many subject and large bodies of interconnected work. I'm missing a navigation for one...

Some possible alternatives for a more structured digital garden are:

Ideally I'd like to just use a static website generator and markdown, in some form or another. I would probably like to avoid having to use Apache to serve it – but I need to look into what my options are, I guess.

I'll keep this writefreely instance, though – but I'll use it more as a regular blog. Time will tell if it'll live or die.
