I'm of the opinion that there's a huge difference in a post trying to determine something not known (i.e. the light leak thread) and a post where a novice is looking for learned information. No one knows anything concrete about the D750 light leak, so throw images and video up there because we're all trying to figure it out. But stating opinion as fact when someone asks for real information is a disservice to the original poster. When you teach do you realize you have to work 3-4x as hard to get someone to unlearn something they learned incorrectly than it is to teach them something new the right way the first time? It's not about nannying, it's about serving the forum rather than yourself. Like it or not there's a big difference between ,"LR is basically PS fleshed out for photography" (stated as fact) and "For me, LR feels like PS fleshed out for photography" (stated as opinion), particularly when you're the first one out of the box.
It wouldn't bother me so much (or be an issue at all) except that you don't think that it matters when you mislead someone, simply because they have a brain and can figure it out for themselves eventually. Easily 75% of the questions on this forum could be figured out by a quick search of Youtube and a full read of the manual, so we can rule out the idea of the OP ever figuring it out for themselves - they want a learned response. You have a lot of valuable things to say, and you're more than willing to go the extra mile to help with a problem, and I commend you for that. But with this I've got a problem with you, because I can't count the number of times I've gone to post an answer to something only to find that you've already dragged someone so far down a path of half-truth that it would take me more time to undo the damage already done than to have simply answered the question directly and correctly in the first place.
But the ACR stuff is the same either way.
