I once mentioned to a professional writer I wasn't interested in a monthly gig because how many times can you write the "Is your j-frame enough" and "Glock vs 1911" article. He told me how many thousands of people buy their first gun each month and this is all new to them. He's right. It might no longer be worthy of being discussed to certain individuals because we've already discussed it in the past to our satisfaction, have a wealth of knowledge and experience to draw on, etc. For many others, they don't have that background, experience, and knowledge so there IS a reason to discuss it because the whole concept is brand-fucking-new to them or they have no experience in the realm and believe IDPA is "training for the street". Surely I'm not the only who meets these people, and *of course* nobody will admit they might have once been that person when they were brand-fucking-new.
I'm always vaguely surprised when people come to a forum, a site that exists solely to discuss things, then wonder why things are being discussed. If the thread or discussion doesn't interest you or doesn't apply to you, it's pretty easy not to have to sort through it.
