LocalWiki, a really easy to use geographically-based wiki, released 15 years ago
I skimmed the page and it seems to be so complicated (comparing with the localwiki). For example, page http://www.lokusapp.com/entry/united_states/texas/mclennan/m... is almost empty (no information) but it is cluttered a lot by empty boxes. Maybe you should focus on the design for a while.
