For what it’s worth, I think most spiders (in my area) are easily identified from photographs. The problem is there are few experts who use photographs, and thus little primary literature and few field field guides. In my mind the solution (and best use of your time), instead of spending all your time agonizing over correcting other people’s IDs, is to examine a lot of photographs of spiders, figure out how to identify them, publish papers about how to do it, and create some field guides. That will improve the crowd consensus.
I’m trying to put my money where my mouth is: guide to identifying common orbweavers from the underside.
