I agree that wiki is probably not the best platform for this. I thought years ago Twitter, with the appropriate search capabilities, could serve this niche. In my experience, it hasn't.
It would be interesting to have a service that could gather together (effectively gather together, with the perfect magical user interface on the other side) a bunch of disparate municipal public data: crime blotter stuff, business filings, real estate transactions, city council actions, what have you. Anybody else curious about this stuff?
EveryBlock tried to be that gathering-together service, but it got shut down: http://www.niemanlab.org/encyclo/everyblock/ + http://www.holovaty.com/writing/rip-everyblock/ "We showed you nearby public records (crimes, building permits, restaurant inspections), pointed you to automatically indexed articles (newspapers, blogs, forums) and provided a sort of "geo-forum" that let you talk with people who lived near you."
This doesn't seem like the sort of thing that belongs on a wiki, being incredibly transient by nature.
Another user mentioned subreddits - that is a good place to search.
