The only other one that we've had so far on this forum was one raised by Richard Dunn in response to a lot of personal critism he was getting at the time. I think that that thread served its' purpose in that it provided some mildly amusing entertainment and it took the wind out of the sails of the people that were criticing him.
It remains to be seen what will happen in this thread. So far it has provided some mild entertainment.
But yes, starting threads about individual members does set a dangerous precedent. Will someone start a thread now with ValvesRus as the topic? Where does it end? With a thread on every active member?
As a general comment on personal criticism, especially in the context of hi fi forums, often the criticism says nore about the person doing the criticising than it does about the person being criticised.
