Thanks for posting this. I have experienced similar. I have found that nasty bug reports are most effective. Good data, and the people are too cheesed off/embarrassed, to follow up, after you address it. Occasionally, it can actually be turned around, and they can become evangelists.

I have integrated a simple feedback form into the app, with the option to send anonymously. That seems to help.

Is that still the case, after being frontpaged on HN (but most comments are probably here)?
