I seriously doubt that Brian's reputation is being ruined over this little thread here on BP.net.
Brian is under no obligation to answer the nay-sayers in this thread. I don't believe a single one of them have even suggested that they were currently in or planned to be in a deal with Brian at the moment, so there's no customer to be satisfied.
This also isn't a BOI type thread either, because there's no "wronged" party here that was wronged by Brian in any type of business transaction. In fact, I don't recall anyone pointing fingers here as having ever done business with or even talked with the man.
This thread has no bearing on whether "I" will do business with Brian in the future (and I sure hope to) and I'd hazard a guess that it will not have any bearing on many other people here who have done or plan to do real business with Brian and not just Monday morning quarterback and critique him.
