Danny O'Brien has a hilarious and serious take on the FooCamp "s00p3r s33krit confab":

In the real world, we have conversations in public, in private, and in secret. All three are quite separate. The public is what we say to a crowd; the private is what we chatter amongst ourselves, when free from the demands of the crowd; and the secret is what we keep from everyone but our confidant. Secrecy implies intrigue, implies you have something to hide. Being private doesn't. You can have a private gathering, but it isn't necessarily a secret. All these conversations have different implications, different tones.

On the net, you have public, or you have secrets. The private intermediate sphere, with its careful buffering. is shattered. E-mails are forwarded verbatim. IRC transcripts, with throwaway comments, are preserved forever. You talk to your friends online, you talk to the world.

This is why, incidentally, why people hate blogs so much... The answer why they won't shut up is - they're not talking to you. They're talking in the private register of blogs, that confidential style between secret-and-public. And you found them via Google. They're having a bad day.
