I was a Bose fanboy. I used to go to their stores repeatedly only to get the "demo" experience. I truly believed that Bose was the way to go. Then I joined the forum on AH, on the website I was able to gain knowledge, direction and finally I based my purchase decisions on input received in the forum. Today I don’t, say “Bose is crap or Bose sucks”, but know that for the price and with a little research anyone can set up a much better performing system.
Notice my signature. Thanks AH!
That said, InTheIndustry, I ask if you have been to other forums of a similar nature? Not just AV, but, car, motorbike, computers, wine, etc. The theme you describe is not unique to AH forums, not even unique to AV enthusiast discussions. If anything fanboys are generally looked down upon in AH forums as is flaming, swearing (moderator controlled), trolling, etc. So there is governance and the moderators have been able to achieve what can almost be called free speech. If there is an open ended question, in today’s connected times, the asker should expect to receive several answers, for whatever they are worth. So when there are several responses in a post, some are bound to be not as helpful as others. If the first response to every post was a complete, cogent and “correct” response to the question asked, there would be no need to have a discussion at all. As mentioned before, when someone recommends a lower costing alternative, the intent is not to be cheap or push a brand, but to recommend a more cost effective alternative that might provide 90% of the quality. (Damn, that was a generalization. But you get the idea.)
What can one do? I'm with Clint on the "Chicklet's" idea. Over time, people in the forum will stand out, whether it is for giving good advice or simply posting to forward their agenda.
Last but not the least, the person who asked the question needs to show some common sense and perseverance. When presented a response like, "speaker A is crap, go with speaker B or C", should not the person asking the question automatically ask, "why do you say speaker A is crap, and how can you say it is inferior to B or C". There will be people who get sent down the wrong path, but in my opinion the blame lies with them for not being diligent in their research.
