> Do you collect as a hobby or for profit?

I never got the idea of being a hobby collector in modern times. Nowadays, everything is available on the Internet for sale, so completing the collection is only a matter of coughing up enough money. How is that interesting or exciting?

I can still understand collecting items which aren't mass produced for the purpose of being collected - things such as history/war memorabilia, rare books fro XIX century etc. There, every item can be unique and obtaining them can demand more from the collector than just typing in their credit card numbers.
