Ever heard this one before? If not, it's because while I didn't wholly make it up; it simplifies what I've had in my mind for a number of years now. Goes as follows:
It doesn't matter what you name your product—no matter how ridiculously absurd it sounds, your product will succeed if you:
- Say it confidently enough!
- Say it enough, confidently!
And if it didn't succeed, it's because you didn't succeed on both counts.
Invisible auxilary #3, important nonetheless:
Kids must do the same too.
Think about how the nutty-sounding anime titles that've succeeded. For every Pokemon, or Chobits, or Digi Charat, or what about the tongue-twisting Azumanga Daioh, the loony Fooly Cooly, not to mention a deceptively tacky Cowboy Bebop, Boogiepop Phantom, and the exclamatory Oh! My Goddess, etc. You wanna be blatant? Dragon Ball Z!
It goes beyond anime too. Think of numerous Japanese food products, the same one you laugh at while browsing Engrish sites. Pocky? Pocari Sweat? And video games? Think for a second about how "Playstation" sounds sooo wrong, but noone really stops to think twice about it because, yup, #1 and #2 and #3 are all in effect—big business! Back in the day, there was also a popular SNES disk system called "Special Partner". And now? Wii, of course. People gonna taunt that name and give it more and more free publicity. 
Ehehe.
Now ponder about prescription drugs for a moment. Think of their actual, non-brand, chemical names. Quick! Can ya think of any?
Which brings me back to Second Life.
Some people have a dig at the name and do the generic, "Haw haw, get a first life!" thing. Which is burned out and invalid, because think about it realistically and positively for a moment: if you have a second life, then you must have—or at least, have had—a first one, oui? So you've actually got more lives than whoever's poking fun (and doing it poorly). I mean, who makes fun of cats for having a proverbial "nine lives"?
Hey, if it worked for "Internet" and "World Wide Web", it could do wonders for us.
