It's by an Australian named Kris, who explains the site's raison-d'être:
"Our ecards are free to send, and they will always be free to send. Wrongcards is not intended for mass-appeal, nor is it intended for the mainstream. If you are reading this, you are probably not a mainstream person yourself, which is good because Wrongcards will probably work for you."
No one will be able to buy t-shirts here with clever phrases on them. No one will be able to attempt to fill up that inner emptiness by buying a hat with a Wrongcards logo. We run ads to pay for our hosting but if we wanted riches, we'd have ecards here with pictures of dogs playing poker, or kittens covered in spaghetti. But then we'd be crying ourselves to sleep each night."
