Good piece from Gizmodo about Path. I recently started using Path myself. The Android app is gorgeous on my Galaxy Nexus. Not a ton of friends using it yet, but the potential is great. Also FYI, Path has the most beautiful office view in San Francisco. I visited it in August on the Zaarly startup crawl (see photo).

Imagine a social network that combines the voyeurism of Facebook with the visual intimacy of Instagram, the real-time newsreel of Twitter with the exclusiveness of a backyard barbecue.
