Very cool news. However, I see something like this and I wonder: "wow, Facebook is valued at over 10 times this purchase price (which is already inflated by virtue of it being a purchasing price)." I don't know what to draw from that; intuitively I see less value in Facebook, but I certainly haven't done an in-depth analysis.
