Joey deVilla joined a Bitcoin mining pool (where people collectively contribute their spare computer CPUs and share the Bitcoins they mine).
Since Saturday he's made about 4 cents mining Bitcoins and about $40 dollars from ads running on his article about mining Bitcoins.
"To summarize: I made 1000 times more money by writing about mining Bitcoins as I did by mining Bitcoins."
