Actually, my original suggestion ("it needs a catchy slogan") was about promoting cryonics, actually, and the example I gave was the first thing that poped into my head, in a hope that others would come up with something better. Instead the discussion turned to the reasons why my suggestion was so awful. In retrospect, this was a classic pitfall, offering a single solution too early. I was taken aback by the reaction, and wanted to know what provoked it and how to tell whether the arguments are valid.

Oh, and I personally would sign up for cryonics, if only I could (not going to go into the reasons why I cannot at this time).
