Greedy Goblin's blog is changing focus a bit. He's covered just about everything there is to be covered on making gold. I imagine there is nothing you can ask that you can't just do a search and find the answer somewhere. I feel like he is saying "leave the nest little birdies and find your fortune. I've given you the tools its up to you to use them".
As a horde reroll in need of gold I recently followed his advice to level my mining up to the point I could mine ore in the areas I was questing in.
This was a rough, "I want to play not mine!" I said. But each time I went back to an area to quest I heard GG's voice (it sounds like a goblin) "Don't be a M&S!". So for several hours I mined ore in lower levels, riding round and round until I got my mining up to my quest level.
The great thing is now I'm actually able to mine mats to have some armor crafted. Win-win.
