I think this could be really valuable, although I wouldn't really restrict it to 3 random people. Flickr for example, have groups that require you to comment on the previous 2 photos to post in that group. That doesn't mean all photos in the group have only 2 comments, many have much more because it creates a culture of critique. As much there has been talk about "Not going dark" for programmers I think this is equally true of businesses. If you believe in what you do enough to tell other people about it then they can help keep you going in the right direction. If you stay in stealth mode forever you could be digging your own grave without knowing it.
