Among the things that I like about mine (I know, I know... like I wouldn't like it) are the fins. The split fin and paddle fin (a Jet, actually
) together in the logo show our inclusiveness (if you can have splits and Jets in the same logo, you *must* be inclusive, eh?
).
The mask-on-forehead shows that we don't hold to arbitrary rules where they don't apply. (If he were in the surf out in California, the mask probably wouldn't still be on the smiley's forehead -- wouldn't be smiling for that matter -- but there are no waves there, so the smile remains as does the mask.)
The pink snorkel... well, that shows... um... our security in our own dorkness, I suppose? We don't need to conform, and frankly, having fun with your gear is a blast.
The blue D represents the lovely blue, tropical water we would really enjoy diving (whether or not we actually go there), and the opposing D is approximately the color-complement of blue. It represents the complement of that nice tropical, bluewater diving and proclaims that even if you dive conditions completely different than most people's ideas of fun, if you have fun doing it, you can be a dork there, too.
The blue mask with pink lens pretty much goes along with the pink snorkel, but it also says that if something works for you and increases your enjoyment of the dive (as some people say the pink lens does to the colors), by all means go for it and enjoy yourself. It may be right, and it may even be wrong, but if it's safe and improves your fun, why worry about everyone else? Additionally, the concept of "seeing the world through rose-colored glasses" is invoked -- Dork Divers should always strive to see the best in everyone (of course, sometimes the best in some people is their tank-side silhouette, but that's not in the logo
).
Anyway, guess that's the short version of the explanation that was lost in the Great Burn.
