Does the Internet bring us closer together?

From Wired:

Technology makes it more fun and more profitable to live and work close to the people who matter most to your life and work. Harvard economist Ed Glaeser, an expert on city economies, argues that communications technology and face-to-face interactions are complements like salt and pepper, rather than substitutes like butter and margarine.

Does the net actually increase your face-to-face interactions with the people you live and work with? Or does it decrease your face-to-face interactions and isolate you behind a computer screen? Please comment.
