Very good points. One thought I've had is that just because some one has been keeping herps for say, 12 years, that doesn't mean that they know more than another person who has only been keeping herps for 3 years. In some people's cases, they could keep herps for 100 years and still not learn a thing. On the flip side of that is the keeper who only has a few years under his/her belt but can and will take in information quicker and have a few original thoughts and observations.
Interesting thread. Just though I'd point out that "experience" doesn't go hand in hand with knowledge in some people's cases.
