Ah, sorry Eric, I meant about why Nick closed Murky down and switched. I know about Wrecking Ball from seeing photos of it under construction on Flickr, and indeed Googling. Reading about the former topic... Hard to tell what's bloggers/reporters jumping to conclusions and what's true.
Edit: Sorry, posted that from my iPhone; I got a chance to read the links you sent and followed
this link from there; explained most of my confusion, from a reporter who actually talked to Nick. Thanks Eric.
