I like the idea at face value, but I wouldn't limit it to business issues (already a forum for that) and I'm not real keen on the validation part. Simply because, though I am an instructor, I have no way (other than the patch on my dobak) to prove it. We don't use certificates and my Sabumnim isn't a fan of MA forums, so validation that way would be out the window. Maybe it just sucks to be me. That would be a shame because I have such "teaching method" discussions with my Sabumnim at least twice a week. I would definately enjoy hearing other opinions on such topics. That said, I have to agree with Andrew that as soon as someone starts with the McDojo stuff, flags go up. Don't need it. Don't want it.
Also, it's not like this is carved in stone. If it gets started and needs to be altered, just do it. If it turns out to be too much of a burden, can it altogether. We tried, it didn't work, it's gone. End of story.
