Shortfalls: 1. Didn't implement metrics to detect delete, trial to get that feedback. 2. Giving up and ranting too early! Marketing is perception, so make sure you make whatever N users happy then tell them to share (it's as simple as this), rinse and repeat. After a ~100 happy users, you'll have a good sample of customer base and it should steadily grow to market potential from there. 3. First release is just the beginning. Your idea is but a hypothesis. As long as they're is still legitimate feedback to work on, the product is still not reaching it's potential (again, ranting too early!).
