Web 2.0 mash-up > Find the latest street junk, in real time

BLOG ESOTERICA: Map mashups are everywhere, but this one could have come only from New York City. And, unlike many others, it has universal appeal--and can even help tidy up the gritty streets of Gotham.

GarbageScout.com is a communal resource where people can submit locations of discarded objects, those charming fixtures of the urban landscape. The blog's motto says it all: "Found treasure map to New York City, a recycler's dream, a cheapskate's best friend, a dumpster diver's companion."
