Most likely reclaiming the bits of metal from exploded miners video cards. As you know, there is a pervasive trend in MtGox and Stolen BTC posts, at first I thought they were trolling, but I realized the actual effect such threads.

Every time one of the above threads get started, a video card blows up. The miner, dejected and horrified, hurls the smoking relic into the trash, only to be recovered and stripped by a gang of recycling hooligans. Please, don't perpetuate this trend, the difficulty plummeting would send the wrong signal, for sure.
