I don't have an iphone and so can't install it, but here is a question: if it's anonymous posting and in a social network, maybe there is a lack of incentive since I don't know who will be following me and I can't be identified. but this is just a guess. what is the closest anonymous social network you're trying to emulate?

btw, when you had your initial idea did you run it by people who resembled your target audience or did you go straight into production mode?

btw, you now have comment that says "never ran just crashed. deleting"
