The problem here is that the propensity to add bugs and features is disproportionate across the user base. Some people get a kick out of adding feature requests and being 'noisy'. Some people have an important or good idea but will never take the trouble to post it.

The problem, then, is being able to sort between this and not only (a) keep the active community members on-side and (b) find a way to flesh out those hidden requirements from less-engaged people.

Of course the other issue is when community requests are not necessarily profitable for the company that provides them.
