Once upon a time, we all knew our neighbors. We knew Daisy, the golden retriever addicted to soggy tennis balls. We knew the saggy sofa in the den, stained by one too many Strawberry Jello spills by the kids. We knew the noise of the lawnmower, the squeek of the garage door or the buzz of the doorbell. We knew just when we'd hear footsteps slogging up the stairway or when the elevator would ping open. Now. in all too many cases, we only see 'neighborhood' on Sunday nights via Desperate Housewives or via Big Brother.One of the best things about knowing your neighbors was knowing things like which house has the twins with chicken pox . . . which street has a couple of persistent gushers bubbling up . . . who has been 'down' with the flu or fighting breast cancer . . what new building/development is going on . . is that creek still flowing or drying up . . . If we all still had BLOCK PARTIES, yes, that remnant of the 50's or 60's or whatever Leave It To Beaver era in which those organic mob-projects occurred, maybe we would have enough information to protect us and each other. Yes, there are a wide variety of domestic and international public health/service agencies that track disease, safety issues, environmental trends, etc. But there are certainly legions of examples of why perhaps even the most ethical of public or corporate organizations seldom tell the whole or even the most realistic stories. Which is why we must tap into the power of citizen journalism . . . or Neighbor-Sourcing to complete a realistic picture of health trends of all kinds, from traditional health care issues (including insurance) to environmental and safety. By harvesting glocallogy tools such as mapping, crowdsourcing and even crowdfunding, we may be able to act more quickly on trends, problems -- or opportunities -- as they occur. We need not wait for the government to announce issues long after it is too late to do something.
