Yes, Ikiwiki was an inspiration to us: besides the goal of supporting multiple revision backends, John also took the idea of caching from it when we ran into performance issues on page loads.

So what motivated this? What do you see as differentiating you from ikiwiki?

Haskell, for starters. But more seriously, the motivation is to have a wiki with the capabilities of Pandoc: a bunch of formats -> a bunch of other formats. One comment already pointed out literate Haskell, which is nice.

Pandoc is excellent. But it's also available for ikiwiki, since I did a quick port a year ago: <https://github.com/dubiousjim/pandoc-iki>. I don't claim it's (yet) as well-integrated as it is with gitit.

Ikiwiki is nice, here's the clickable link: http://ikiwiki.info
