"The key to intimacy is just knowledge. Path pulls that off by allowing you to see who looks at your posts." There's some good thoughts in here about why and how Path is carving out a niche.

"The days before Christmas, friends were sharing photos of the build-up, putting up the tree, wrapping presents, sitting on trains getting to parents houses, cooking hams. To me there was a real sense of flow, connection, joining in of everyone’s experience, a bit like a pictorial version of twitter to some degree. Christmas morning was almost magical.
"The previous year on Flickr was almost as magical, once people had a chance to sort through the 100s of photos they’d taken with their dSLR, pick out the best ones, run them through lightroom and then get a chance to upload them. It was nice to look back on the Christmas mornings that people had, rather than having."
