Viridian, your point is well taken, but I think John assumes most people know Audio Connection is a Vandersteen dealer (largest in the country?), I don't think he is motivated to hide the fact, though it is probably good form to have manufactuers and dealers have "signature" requirements disclosing the fact.
Not sure how you get disclosure of another type of finacial interest - folks (users) that own equipment they are intending to sell, or want to be one day, and pump up a products virtues for the day the list the item on Agon - to see through that takes careful reading over time and getting to know the community members, but this concerns me more as an undisclosed "financial interest". Dealers are easily rooted (ratted?) out by other dealers:)
