I’m with Om, Path is no Instagram. I’m a fan of niche social networks, but Path feels like it’s going to stay niche. In real life, users belong to different circles of friends, family and colleagues for different contexts. Path has an elegant mobile application, but its very narrow focus on two-way sharing with a select group of friends doesn’t allow that context specificity. And its 2 to 3 million users guarantee that too many of a user’s network won’t be there on Path. Facebook, Twitter, and Google via Groups, Lists and Circles give users more fine-grained control over context groupings than they can handle. As Om points out, Path doesn’t seem to have that magic mix of social and broadcast models, nor a defining addictive behavior. It’s got $40 million in new funding to help figure out the latter.
