What motivates people to collect? I can feel the impulse within me and generally resist it, but haven't given it much thought.
This is a question that I personally wonder about myself, and I'm not much of a collector myself, so I might not be able to give a great answer. I think that community is a big part of it. Collecting things is often very social: You buy and sell from other collectors, and talk online and in real life with other people in the hobby.
