Clay has been writing in his blog off and on for a while now, but he has never officially "released" it for public consumption. At one point, Sean stumbled upon Clay's experiment so we've all been "secretly" reading Clay's stuff this whole time.
Now, however, Clay has officially flipped the switch.
Clay is an electrical engineer (although we won't hold that against him, no matter HOW much bad and ugly software he makes) with Bose up in the Bostonish area. Clay also "dabbles" in manufacturing process engineering. He just bought a home which he's slowly and surely fixing up.
Now only Mike is left.
