Metcalfe's law
Two telephones can make only one connection, five can make 10 connections, and twelve can make 66 connections. Metcalfe's law states that the value of a telecommunications network is proportional to the square of the number of connected users of the system (n2). First formulated in this form by George Gilder in 1993,[1] and attributed to Robert Metcalfe in regard to Ethernet, Metcalfe's law was originally presented, circa 1980, not in terms of users, but rather of "compatible communicating devices" (for example, fax machines, telephones, etc.)[2] Only more recently with the launch of the Internet did this law carry over to users and networks as its original intent was to describe Ethernet purchases and connections.[3] The law is also very much related to economics and business management, especially with competitive companies looking to merge with one another.

What's in a wine label? - Wine
These days many enjoy buying wine with labels that feature animals: kangaroos, penguins, fish, lizards, and loons. These “critter labels” don’t just happen by accident — research shows that American wine consumers are 40 percent more likely to buy a wine with a cute animal on the label when compared to a straightforward label that gives the standard information: the name of the producer, the name of the grape, the name of the place where the vineyards are located, and the year in which the grapes were picked. But whether we choose our wines based on the cute factor or on the basic label facts, most wine labels give us minimal information; it’s up to the consumer to know about the vintage, the area where the grapes are grown, etc. Sometimes the back label of a wine is reserved for marketing the wine, and in the process of trying to hook the consumer with spinspiel, we learn a bit more about the origins of the wine and the philosophy of the producer. Let’s take a look. Filtration: None
