Viral Marketing Works !
You obviously know these viral marketing schemes, where you create a social network that will try to establish a brand via referrals and other people discussing it.
A brand will become more popular because lots of people will be pointing to the new products or features.
Microsoft also seems to have figured out this method. They demoed one of the most interesting features of their product at the Olympics
And according to Matt it seems like the FrankFurt airport also is showing off this feature. Obviously this isn't the first time this virus pops up but it seems to become popular again
