San Diego Fires on Google My Maps

Nick, a classmate of mine, pointed out this interesting use of Google My Maps for disaster reporting by KPBS News in San Diego. KPBS is also maintaining a Twitter stream for updates about the fires, which is the most useful potential use of Twitter I think I've seen. Has anyone seen any fire mapping systems on the web that integrate discussions? Requests for missing people, perhaps requests by evacuees for ground info on their homes?
