Nobody is banging on you John and Eileen - You're right its all about helping Redwood owners enjoy their rigs.
However, it has benefits both ways to post by topic. First and foremost is you as the poster get the best responses because it shows up in the topic line and those with knowledge of that can jump on it. If its buried in some other thread with a different topic, it doesn't get the attention from those with similar experiences or knowledge, especially if they don't have an interest in the unrelated topic it happens to start under. It just simply gets missed.
The second benefit is it is far easier to search for something by topic, than to try and find key words in every thread. I've often referred back to topics that had part numbers or fixes, and my brain could never index them if they were in a topic about something else non-related.

For some reason I end up replying to a topic but it shows up on a completely different topic in the forum that I had opened earlier. I'm sure its operator error on my part, but more than once I end up talking about something that didn't exist in the thread it landed in.
