Problem: What does this quote mean?
Unlike law-enforcement officers or garbage guerrillas, the archaeologists of the Garbage Project are not interested in the contents of any particular individual's garbage can. Indeed, it is almost always the case that a given person's garbage is at once largely anonymous and unimaginably humdrum. Garbage most usefully comes alive when it can be viewed in the context of broad patterns, for it is mainly in patterns that the links between artifacts and behaviors can be discerned.
