Miriam Gonzalez is certainly worthy of the Playmate of the Year title, but don't bother casting your vote, especially with the 900#. It's a well-known scam to make money for Playboy.
In other words, in this case, your vote *doesn't* count. The decision is made by Playboy editors, and ultimately by Hugh Hefner himself. The decision also factors in how the Playmate comes across in public, how well she speaks, etc.--neither of which can be decided from a pictorial.
Miriam may well win (and I hope she does). But it won't be as a result of any votes by readers.
