I haven't been on LGT long enough to comment, but I have seen the same trend happen on other forums I was once proud to be a part of. I think it stems from having more and more younger, less experienced people join forums. These people come from the 'Spoon Fed' generation. People that lack the imagination necessary to foster innovation. They grew up with programmable calculators so they didn't have to learn long division.
You can see the trend not just in the automotive aspect but everywhere in the world. They want the quick fix without learning about what the fix is.
