I think this is brilliant social satire come to life. Can there be a block chain of people who "trust" a source within the net and where central claims originate?
There is a .zip you can download, and a link to give it access to your Twitter account. That's enough to make me think it's legitimate :) If you are brave enough to go through either of the steps, let me know what's at the end of the rainbow.
