This post by Ben Hyde, Fundable, at “Ascription is an Anathema to any Enthusiasm” is worth a read. It explains a variety of collective action problem in very clear terms, and then suggests that startup fundable may help to solve some of them.
Great start, too:
Why don’t neighborhoods have a collectively owned tool shed? My neighbors and I own the most amazing amount of idle capital equipment! We each have our own hedge trimmers, snow blowers, lawn mowers, etc. etc.
Of course the real answer is that everyone wants to use the lawn mower early Saturday morning while I'm trying to sleep.
