Great work LocalWiki. This is a good way to build hyperlocal mobile/sms apps. I find myself usually scraping data off wikis, massaging it a bit, then building my own api endpoint to feed the mobile app.

I hope this one linked here is actually being built, can see a lot of folks re-using it. https://trianglewiki.org/Wanderful_App

Next step is to build a mobile app that feeds data back in (POST/PUT). Like YokoZar points out, it's a Sales task, not necessarily a difficult technical one.
