Thanks for your input guys, but it really does not address my question. I understand that youse pay no attention to smoke rings, but I am wondering why it seems NOBODY is paying attention to them now. Like you point out, they mean little or nothing, yet this irrelevance is not the same as their disappearance from discussion. Hell, let's face it - as the Sturgeon quote in my tagline indicates, most of the stuff on this site has little relevance.
