are you suggesting people shouldn't have the right to express whatever they think, or that none is valid?
Not at all. It's just that 1/after over 1,350 posts, anybody coming relatively fresh to the subject simply hasn't the time to read them all, so the same questions get asked and theorizations get posted over and over and over. 2/The people who have been here from the beginning are no longer bringing anything new to the subject. 3/Many of the real, knowledgeaqble professionals--I'm certainly not one of them, but then I don't post on matters of true import--have moved on, realizing there's nothing new or important to say. And 4/Many of the professionals have been replaced by curious frequent flyers, model builders, flightsim players and Cessna 150 pilots.
Hence random noise. My rule of thumb is that when a thread begins to top five pages, it's time to move on. Everything important to say has been said.
