BitcoinMessenger - Send a public message using the Bitcoin blockchain (btcmessenger.com)

What will you do with the dust?

How does this work?

I don't understand the relevance of the title to the service, but it seems like an interesting way of using the bitcoin blockchain to strongly time-stamp messages.

Also the fact that it costs you money to send a message and the more you spend the more "important" the message is happens to be interesting.

Where do you write the message?

So wait....each time someone sends a message with this service...they are also just handing this guy some money? Genius!
