I wonder the same about the Aussie salt water myth. I think it just comes down to the fact that some of us get different results than others. Some people may have success with regular salt water, and others may lose their Straws unless they give extra strength salt water. Or perhaps it's a panic thing. This is something I've been thinking about lately. When compared to PPs, Straws are extremely exotic, and hard to come by/expensive. PPs are everywhere, and fairly cheap. So, Straw deaths are more hard-hitting because there's always the question of when we'll get more and how much they'll cost. (That, and when the population of a species is smaller than others, deaths stand out more. When you lose 1 PP in a crowd of 30, it isn't going to hit as hard as losing 1 Straw out of 3.)
This could also be what's causing the Aussie salt water myth. With the only supplier being shut down at the moment, there's no way those of us in the US will get more if our Aussies die. This makes us want to take the best care of them as possible, thus turning us into paranoid maniacs.
