Form my perspective: sometimes when I report a bug it's more so that other users don't waste their time troubleshooting it than to have it fixed immediately.
Finally there are issues like these ones that are not clear cut but that I can't investigate myself because it requires time and resources (they eventually cost me a few bucks running instances for testing purposes).

You guys have a good product. I think that the promise of not having to manage infrastructure hit a cord with many people. However you do have many bugs to fix to make the platform more stable and (non intentionally) discouraging people from reporting issues will make things improve at a slower rate.
