I really think this hobby is directly influenced by the availability of frogs in pet shops. If it is relatively low-priced and easily available at the pet store, more people will go for it. But what upsets me is that most pet shops do little or nothing to let the consumer know about proper care, or they give them simplified and incorrect care tips. This leads to the animal dying prematurely, and the customer becoming discouraged (the same applies for new quarium keepers who don't cycle their tanks, they just throw ten fish in, then they all die of ammonia poisoning.) The happy herp keeper will get the right knowledge, buy a herp from a reputable source, and then get addicted like me and buy more and more when financially able and knowledgible enuff to care for them. The idiot who does no research will go buy a bunch of different frogs, throw them in a ten gallon tank, and b*tch when they all die. The idiot could be redeemable if he goes out, educates himself, and tries again, though.
I think the amount of "hardcore", educated herp keepers is directly linked to the quality of education that they are given about their charges. Sure a few will impulsively buy a frog from the corner pet shop, but I think that the real serious keepers are the ones that learned about frogs beforehand and know what they're getting into, and don't lose interest.
