One of the great things about OSS is its transparency. This is also a great response to critics of any particular project, which is "instead of talking so much, why don't you shut up and help?".
I'm guilty of forgetting that there are real people behind most projects. With commercial software this happens a lot more and is disguised as "I'm a paying customer and I expect good service", but there's no excuse, honestly, for criticism that isn't phrased constructively and considerately when the product itself is free.
Fnar fnar fnar.
