I agree. HOWEVER...
having the sections makes it easier to find things if you need to browse. in other words, sometimes if you don't know exactly what you are looking for and you don't know which keywords to search for, it might be really hard to find something. That's my only comment about this. Otherwise, it's a good idea.
In other forums, the members are usually pretty snarky about duplicate posts. Sometimes you'll start a new thread, and the response will be "This has already been discussed before". I hate that. But I don't see that happening here, so I say go for fewer sections.
