I find it surprisingly sticky and think it could be great. I am also not prepared to accept the assertion that it has failed. I will agree it's not as successful as it could be though. For one thing, they only recently added the capability for a non-owner of a shared stream to post to that stream. I think that is critical for a creating a social experience. If I were running the product, I would: 1. Integrate the suggestion to create shared streams, or add photos to shared streams, more deeply into the photo-taking and saving experience 2. Build more identity around the connection between the user and their presence in shared streams. (For example, photos can be "liked" with the happy face symbol, but you can't look at a person and see all the photos they've liked.) 3. Market it. 4. Android app.
