What is wrong with posting such right where you posted this post?
Just my own opinion, and speaking for no one but myself, I am all for fewer rather than more subsections. The more special categories we have the more it gets divided into little narrow interests. I am attracted to threads by their title and title content, not what subsection it is in.
For example, I do not wind pickups and do any luthier work, so I never visit those sections. But in the activity stream, a post in one of those sections can catch my eye because it also impacts other areas. I then go to the post, which I otherwise wouldn;t have seen.
