I just got asked this question:
Is it OK to ask people for feedback about my product?
Here was my response, with a minor addition:
No, please don't ask for general feedback.
I'd rather that it not get too self-promotional, as The Backchannel is just getting it started. If you have a specific question about your product, then maybe fine to ask that, but I wouldn't ask "What do you think of X?" otherwise the entire forum will end up with those questions.
What do you guys think of that? The right policy for now? Maybe in the future I'll add a section where this kind of a thing is encouraged?
