I've bought a popular video game, which has a supporting smartphone app to enhance the experience. The app doesn't work on my (relatively advanced) device, so I complained via the publisher's community forum — but didn't get a response or solution. Apparently this isn't just me.

And last week, I downloaded the frustratingly difficult but addictive Flappy Bird app game as did millions of others. But after its soaring and rapid success but equally high online antagonism rate, its developer has for the moment taken the decision to withdraw it for download by any new players.

It got me thinking — either for users, or businesses, is too much feedback just too much of a headache? If so, how can this feedback be navigated to facilitate genuine use or improvement? Is there a role for a "big feedback moderator", and what would this role look like?
