I am now, have been and will be wrong

Can this work? Or would this end up in group think?
Or would we have the same problem of having people degenerate into profanity and outrageous comments?

Don't know, and no one seems to have tried it before.

The most probable result would be a threaded/usenet type of response.
A lot of 'gut reaction' type comments. Which are the ones that matter most for an executive summary/initial b-plan.

Should probably insist that the documents be 5 pages or less, something most people will simply ignore, but it will give folks leave to scream at the writers that the document was too long.

Should give people the option of getting an RSS feed, or an email when a comment has been posted on their company.

This would be an ego thing.

This would also drive lawyers nuts, or more importantly, make it completely clear that everything that was said and put on the site would be open knowledge. Up to and including any responses by the company.

IP issues, etc. won't be covered
