If you could make just one wish for the entire world, what would it be? Austin Hill wants to add your wishes to his collection and hopefully raise some money for charity along the way.

The aim of the Million Dollar Blog Post is to gather one million comments, each containing a new wish. 148 people have taken part thus far, leaving comments like, "My one wish for the world is for the harmony we are capable of within ourselves to be one with the harmony of the universe," and, "I wish people would forgive each other."

For each comment left on the entry, Hill will arrange for $1 to be donated to charity. His team has already donated $2,500 to groups like Project Hope, CAMFED, and the Wikimedia Foundation. It's a fun social experiment and a great way to contribute to a worthy cause. Once you start reading through the wishes, it takes on an almost PostSecret-eque voyeuristic quality.

You can help by making a wish, sponsoring someone else's wishes, or by simply spreading the word.
