Very cute article Kevin! I started out like you did, I couldn't understand why I would ever buy pins just to trade, I bought them for my collection and would never entertain the idea of trading for random pins. Then I got a few extra/free pins and discovered just the fun of trading to trade. I don't do it very often, but whenever I see pins to buy cheaply (ebay or a store), I get a few to have in case I see something I like, which, if it doesn't fit in with what I collect, I end up trading again. Sometimes it's just fun to interact with the CM's, and every once in a while I do find something that does fit in with what I collect. What can I say, it's just fun!
