I don’t think talk, or toxicity is nearly the barrier that it is being made out to be. But rather basic human behavior and lack of interest is the barrier. In municipal communications, it appears that there is about 80% of the population that simply won’t process the communications you send them. My gut feel is that it simply is not part of their daily routine, and they are so bombarded with junk mail, door spam, Facebook and other online messages, that none of them reach through to their day to day consciousness.
A city can have a potentially controversial zoning change request, that may be good for the city overall, but a nuisance for the immediate neighbors. You can insert flyers in their water bill, you can post notices on the city web site, Facebook page, and twitter. You can put official notices on the front door of all the adjacent houses. You can post official notice in the official newspaper of city record, and you can even put signs on the street corners. For a project that may have 50 directly neighboring residences, maybe two homeowners will show up, and once it is decided and underway, the bulldozers being a difficult to miss indication of change, you will finally get 5 to 10 homeowners who show up and chew out city staff and council members for not giving them a heads up about the project and hearing.
So, I’m really not sure what each committees bulldozer is, but my experience says that unless you identify your bulldozer, and make it visible before the decision, you may need to realize that talk reaches an unusually high percentage of our population, compared to many other options.
