While I agree about the credit card number + random form = iffy part, I think you're being too hard on the app itself. Sometimes a simple idea implemented in a very stable way is a good product. Also, I think your tone might not be ideal for what you're trying to do -- it sounds like you're mocking the developer or at least asserting some superiority over them. Even if you're right, sometimes ideas are better expressed with a modicum of humility. (I realize it's hard to project an "attitude" over the Internet, so I just thought I'd let you know what kind of attitude I felt you were projecting).
