Go to: Diesel Sweeties by Richard Stevens
Should have posted this earlier. It does seem inevitable that for social networking sites, many users get sucked into the game of accumulating the largest possible number of online contacts. That's probably already the case with Google+, regardless of what kind of "circles" are being used to manage one's contacts. A hierarchy of sorts develops anyway based on popularity and name recognition. Doesn't Leo Laporte's ego get stoked from having so many hundreds of people placing him in their circles? In how many new ways is G+ going to end up fortuitously fostering this behavior?
The PC Weenies has its own funny take on the subject.
