Why?
There's already one dealer on here (well, part dealer, full time mechanic god, Sir Dave of Scotland) who was unaware of the facts so if a couple of other dealers on here get educated it can't be a bad thing. If I know about it and I'm a proverbial pup, everyone should know it.
And yes, as you have pointed out, trying to keep things "secret" from the entire internet is a futile task. In any case, I think people should come on here and see that most of us do the job right, know what we're talking about etc. It inspires consumer confidence in the industry.
