Yes, they are permitted and even encouraged. The science and the protocols of diving change with time and discussions that highlight these are incredibly helpful. Quite often, what was not a good idea five/ten years ago is common place today.So my question is: Are questions that I could have found the answer to by doing a simple web search permitted or not?
Fortunately, a lot of what powers ScubaBoard is unbridled passion. People want to share and learn and are incredibly passionate about (to them) their well thought out approach to diving! Sometimes, what we see as a given has not been thought thru by others and so they have not arrived at our, seemingly enlightened, position. It's good for all of us to be circumspect not only in how we dive, but in how we answer questions. Confrontational posts are almost always taken the wrong way. It's better that we learn to tolerate those with skills different than ours. If we are truly superior in our skills, it won't be long before others will be chiming in to sing our praises.
