When I was looking at blogging the way I wanted to, I came across Markdoc. This brilliant little CMS is likely the most seamless way from plain text to a wiki. It brilliantly encapsulates the facility of a relatively low-tech tool with a functional programming approach to managing your data: don’t sweat the structures, but be able to compute displays over them quickly – c.f. org-mode.
I’ll be playing with this over the next few weeks, for sure!
