The social Web is revolutionizing the way institutions operate, and the way people communicate, but in the end it might not have much of an effect on the core social group you depend on for true friendship. You can maintain a giant number of weak ties to people on Facebook, Twitter, and whatever comes next, much like you can in a giant company. Strong ties, however, require constant grooming. People who use the number of friends they have on Facebook as a metric of their social standing are fooling themselves. You can share videos of fainting goats with hundreds of acquaintances and thousands of followers, but you can trust a secret only with a handful of true friends.
