As users, it's hard to say how Cake sets their priority list. Recent threads indicate that the forums are only a small piece of the puzzle. It's obvious that bug reports are another piece and the issues that get discussed here can sometimes lead to quick fixes. But I don't think bug reports are a primary driver.
During the last NAMM, Craig Anderton reported that Noel was showing off Sonar using Bluetooth midi input. I'd never seen that as a feature request, but sure enough, it's a new feature in the most recent Sonar release.
My observation is that feedback from the early release is the most potent input users have. The majority of issues reported get sorted out quickly. It's a form of real-time bug reporting that seems to work for Cake and the user base.
