how they evidence their claims
This is exactly the point of this thread/poll.
It is obvious why you are posting this poll, and obvious you are frustrated with f3nikon giving opinions you disagree with.
While a particular situation, or repeat of many situations, might trigger an idea - it would be intended to apply to everyone, for the benefit of the quality, and verifiability, of information posted on this site. It's not aimed solely at one individual.
However have you actually thought how you would go about implementing your idea? Where should it stop?
Well....let's look at that....
Instructors should post their certifications before replying to divers?
They already do. The instructors panel is set up exactly in that way. You have to show your credentials to be accepted as an Instructor (or DM) on this board.
People offering advice on their local diving should post utility bills to prove they life there?
I don't know about utility bills, but if someone posts unsubstantiated stuff about some local issue or other, what's wrong with asking for proof?
Medics and Doctors should post their degrees and training before offering advice?
Absolutely. Although I'm fairly sure that no Doctor or Medic speaks in a fully professional role on the board. There would be all kinds of issues of responsibility if the advice given here could be viewed in that way. In my experience though all the Doctors and Medics who post here make it VERY clear who they are - and the limits of their advice. I've yet to see a charlatan spreading erroneous advice (although, sometimes non-medical members do do exactly that. Thank God we have some here to control that.
Public Safety divers should post pictures of corspes they've personally recovered?
Why? Again...like the Medics they know their own and are very self policing.
Spearfishers have to post corrobated evidence of their catches?
What's special about a spearfisherman? Have spear...will hunt. Big deal.
DIR divers have to post pictures of them sucking down 3 litres of any kool-aid (ok ok I'll stop here)
You probably better should. They just got their own even more protected forum where you actually need permission from the guards to get in. The control is fully in place.
My point is why should photographers have to provide a higher burden of proof than any other member of the Scubaboard community posting on this board?
As you can see they wouldn't. I already said - it's not about a closed or restricted forum, it's about whether people should be held to some burden of proof if they start making claims that can impact others somehow. With photography it's not life or death....but it's definitely potentially financial. What's wrong with requiring people to back their claims up somehow?
Often the best way in photography is to see if they can walk the walk - and we do that by looking at the pictures!
Any self-respecting photographer is quite prepared to put their photos on view. What's the point otherwise? Self-indulgence?
Anyway. It's not just how I think about it. That's why it's a poll. To see what others think.......
