First off, the forums are richer by having brokers and realtors on them, and there’s enough loud bears who will immediately and loudly object to anything they perceive as biased.
Second, there’s nothing wrong with HLS, SDR, sdr, (or for that matter) our site owner accepting business they get by offering reasonable wisdom on this site. They’re putting in time here, just like the dear Prof, and if they get good press for doing so. Besides, I’d much rather do business with someone I’ve gotten to know on this site than flip open the phone book and take my chances.
