I should probably update that post. I took it down because of some issues with my hosting and then never really got around to bringing it back up. at the time, it only had about 20-30 items though.

I can tell you the export to HTML functionality is solid, but for something like a wiki you really need searchability which as far as I know zim templates do not provide. The available templates are also not responsive other than maybe the eight-five-zero theme that i modified for my site.
