OK. UI is great. But whats the app doing? Telling you it is your own journal and allowing occasional sharing? So a personal blog that works from your smart phone and thus lets you do stuff that Wordpress won't? I like it, I must say. But why would users use it? Self gratification? What is their business model? A la four square? Will they eventually have checkins and deals?
