Tinystomper, at least acknowledge that people have suggestions. Suggestions are good. It means people are showing an interest in what you have to offer. In fact, it goes beyond that - it means that people actually respect the work you've done already. As a developer, you don't even have to implement those changes. People want them to be added, but the very least they expect is respect and acknowledgement. If you're using a 'customer service front', you've already failed since you resorted to attacking your users instead of engaging them in conversation or discussion. Even when others start shouting at you, you don't start shouting back, not if you're trying to promote something or 'take a customer service front'.
If you're prepared to listen, then perhaps we could help you out. Someone, later in the thread, create a clear, concise and organised list of suggestions (I'd do it, but I doubt I'll be back to this thread). If he won't listen to that, then it's quite clear that he's not looking for feedback at all, and that he's not going to get anywhere. He may have talent, but if he's not prepared to listen, then it'll be going to waste once people realize how their words fall on deaf ears.
