Hackpad as a wiki

Have any of you guys used hackpad?

I’m considering using it as a wiki and wondering how it might fit this purpose. hackpad has open sourcecode which is also attractive.

I played with it very briefly prior to the dropbox buyout but never really looked at it after. No idea how well it would work as a wiki.

HSBNE’s wiki is an instance of Gollum, which is a git backed ruby app written by github.
