There is a fundamental problem with that - this list isnt a support list, its a list of and for people who use CentOS to talk about CentOS. By thinking of it as a one way support system you have reduced the list to essentially a bugtracker / issuetracker / support thread and that in itself defeats a very large part of what the list ( and community herein ) is about.
Yep, that's kind of what I was meaning by saying it was a more "formal" approach, but you said it better. :)
