I agree that you shouldn't go out to the extent of bragging - as jacquesm points out your business is still vulnerable. Don't let success give you an inflated opinion of yourself.
I disagree with prescribing the opposite extreme. The most successful products don't become successful because nobody has heard of them yet. It's selfish to not share what you've learned with others, and just as bad it deprives you of opportunities to learn from their feedback.
The best don't become that way by being kept secret. They're the best because they add value to the service by being good at what they do. If your level of dedication to making good product is clonable, you're dead already.
