I think this system is amazing and I am a huge fan. I would like to suggest this platfrom to a company I know who has tried "forums" before and failed.
I think they could really use this for their general tech support but users could also contribute and vote up and down things the same way they do here.
Does that go against the spirit of the site?
Could the group be focused around using a product just as it is focused around unix/linux or focused around cooking?
*Clarification: Couldn't it be done "as a stack overflow site? I mean, couldn't someone say, I have an Open Source Linux product. Would it be "wrong" to let users use this format for interacting and answering questions? *
