I voted yes even though I probably wont ever bother reading more than a paragraph or two, if that.
I've made a few million (about 4-5mil) with little to no effort on making gold; I would call myself an opportunist (and a rather lazy one at that to be honest).
If you are going to make a gold guide, my advice is to focus on the main bulk of where you get your "consistent" gold; that is to say don't go into great detail about old raids, old matts, or transmog items, a simple list is fine. It seems you make most of your gold from TSM, so make a TSM guide, call it that and focus on that, with maybe a subsection regarding the rest.
Best of luck...maybe if I get desperate I'll give TSM a shot
