This. We don't need a slew of startups to solve this problem; it's called talking, and it can be done via any of several existing {meat,cyber}space communications channels. (I'm hardly a Luddite; rather, I think there's a lack of appreciation for basic interpersonal communication as a powerful technology in its own right.) I don't remember where, but in recent memory I saw an article about an apartment building where residents would mark their doors with icons representing appliances/tools they were willing to share - a simple solution for an easily solved problem.
