This article, from Jon Udell, describes how he used online services to highlight a section of trail that he'd cleared of trash. He sent the map, along with a letter, to his local newspaper, to encourage others to pick up where he left off. Things like this make me wonder whether online connectivity will, in the long run, favor the civic-minded: people who don't care about things like this won't be affected much one way or the other (they'll just continue to consume), but people who do will be able to make ties with each other more easily. Mumble mumble preferential evolution mumble game theory mumble...

Udell closes with a quote from Gibson: "The future is here, it's just unevenly distributed." I think another would be just as appropriate: "The street (in this case, the hiking trail) finds its own uses for things."
