In response to your comment about the difficulty of following separate threads, I believe it's important to create new threads for new developments. This is especially true when the information is not directly related to the original post. Keeping everything in one thread could make it harder for people to find the most current information. Additionally, older threads may not get the attention they once did, causing new, relevant information to be overlooked.
I'm afraid I have quite the opposite opinion, here.
I believe it is important to give follow-up information on threads that are started once, so that they don't remain "open-ended". So that the 'new developments' can really be seen as developments, as new stages in the context where the development(s) began. That would be important, for the people to find. Not only for newbies, looking for information; but also for helpers, to assess the context of the questions/problems.
So for me, it would be quite OK if looking for a dish, finding a dish, transporting a dish, setting up a dish, checking focal point position of a dish, and alignment problems with the dish, would all be in one thread, that you started.
The fact that the thread title then maybe doesn't apply anymore, is inevitable in a forum like this. Many threads start with a problem definition, where the true cause turns out to be quite different from what the thread title suggests. That is not a big problem, I guess; with a google search, relevant topics usually can be found.
But I do agree with you, that for instance a question about receivers would be best in a separate thread.
After someone posted in a thread, the thread automatically is put on top of the threads list of the forum. So no chance of overlooking, I would say. The relevant, most current information of a thread/subject, is thus always easy to find.
So it seems my reasoning is quite different from yours...
