2nd dependency, Facebook deciding that the app violates their intent, I never thought it. If Facebook in fact does that, I don't think I can do anything about it.

1st dependency, dependency on mobile devices, yeah, I regret starting with the mobile app. Though this is a hybrid app, considering the time that I can spend on this and my pace, I might take nearly a month to make a web app. And now, I am not sure if I should go ahead and release the Android version, or work on the web app and release web app first. Any suggestions?
