NameCoin was designed for more than just cryptocurrency aka money, currency, trading for cash - whatever it is you want to call it.
It is much like BitCoin because it's built on the original BitCoin source - BUT - it has quite a bit of additional things added to it for DNS functions.

However - All of you that say it's NOT "money" - I'm confused at your reasoning. I can go to an exchange right now and trade Namecoins for USD ($$) just like BitCoins. I can also trade NameCoins for BitCoins and vice versa.

Might not be much - and it might never get as high as BitCoin one may argue (as it's main purpose is NOT to be "Another BitCoin")...but the fact that it's built on BitCoin and you can merge mine both via pools, and exchange it for Cash money - I don't see how you can argue that it's NOT the same as BitCoin with more features/functions.
