If you’re like me and you’ve heard a lot about Bitcoin these past few months yet still have no idea what it is, read this piece by Felix Salmon:

A few days ago, the value of all the bitcoins in the world blew past $1 billion for the first time ever. That’s an impressive achievement, for a purely virtual currency backed by no central bank or other authority. It’s also temporary: we’re in the middle of a bitcoin bubble right now, and it’s only a matter of time before the bubble bursts.

It’s interesting and enlightening.  It also makes me glad I’ve been in the dark on Bitcoins until now.
