An Architectural Digest for the young, trendy studio dweller — or the eco-minded, two-bedroom couple — Apartment Therapy is a how-to guide for restructuring one's life on a smarter, cleaner, hipper scale. Visitors get to see how others have done up their apartments — from decor and green space to child gear, tech hookups and cool furnishings. It's all about thinking outside the box — taking a 550-sq.-ft. pad in New York City or a similar small space in San Francisco, Los Angeles, Chicago, Boston or Washington, D.C., and sharing how you made it breathe, stretch and pop. As the blog's mission statement proclaims, "A calm, healthy, beautiful home is a necessary foundation for happiness and success in the world." In addition to virtual-apartment ogling, be sure to check out "Marketplace," where you can specify a city — and even a neighborhood — in your quest for that perfect couch, lamp, cookware or centerpiece.
