If you are a member of an online forum where you discuss a particular activity over a period of years, and you personally collect thousands upon thousands of dollars in accoutrements for said activity, then it's safe to say you're a hobbyist.
Now the old farmers who buy tubs of codger burley along with cobs and Grabows at the local discount baccy store here in town, those guys are just smokers.
Yes I understand that the "pipesmoking as hobby" thing is a bit irksome, but the truth is, yes we are ALL hobbyists, or at the very least, tobacco aficianados, and I'm not sure there's any real distinction to be made between the two.
