Ashley Mitchell, an IT professional from Paignton, Devon, England was recently charged with hacking Zynga's Facebook poker game. He admitted accessing Zynga's computers and putting 400 billion credits into fake facebook accounts, which he was then selling for real money. I think Zynga is trying to have its cake and eat it, too. On the one hand, they do not put vigorous security controls in place because it's just a game and it's play money. On the other hand, they want to cry foul and make analogies between virtual currency and real currency when someone bypasses their weak security and starts making money.
Facebook is savvy about time zones and the fact that its users span the globe. But notice this conversation I had with a friend. He sent it at 12:39am on October 21st. I replied 3 hours earlier. Now, if you look at our profiles, Roy and I live in the same time zone. Normally this would never happen. But, I happen to be in the UK when this happened. I think I replied a couple hours after his message, but at you'll see, it's essentially impossible to know, given what I see.
I was just reading "Five Clues That You Are Addicted to Facebook" on cnn.com and it occured to me that Facebook should really be considered in the same light as television.
