In my experience when people ask for a critique of something completely new, they're asking (usually without knowing it) for the high-bit: Does this completely suck, or should I keep working on it? Unfortunately people too often respond with only the low-bits, forgetting to add "but these are nit-picks, the overall idea doesn't suck, and you should keep working on it". At best that's frustrating, because you only hear low-bits when you wanted the high-bit. At worst it's a disaster, if you misread low-bits as high-bits and give up on something promising.
