Well...
The director of Cloverfield apparantly has something to do with Slusho Drinks, and their motto "You can't just have Six!" Either he owns this literal company, or it is in another movie which relates to Cloverfield itself.
You can actually buy t-shirts and things from this company too. But anyway, the website deals with clues relating to Slusho drinks, and other things. You just have to look at the pictures very carefully.
Here's a hint. Look at the picture with the man and woman in it with there hair a little "entwined" due to the angle the photo was shot at. Look between their hair, what do you see?
I think the director is trying to relate this monster and/or movie itself with Godzilla, and in a way bringing the monster back for some future movie... My 2 cents.
