We're born worshiping ourselves. Now we just get to do it a little more publicly. At least since it's a closer group of friends and family on Path, those you "friend" will be more likely to know your true character, and they'll be genuinely interested in what's going on with your life.
Will they? Is a gorgeous, lovely, stroke-able app for this compelling enough to get people to use it? Use it all the time? Make it a primary means of communication?
I don't know. I'm not saying it'll catch on or be used. I'm just saying those are the things that make it more compelling than facebook to me. And pointing out that these new "social networks" aren't making us worship ourselves anymore than we used to.
