People are funny, he will NOT share his knowledge. The true problem with him is competitive advantage. Anybody can buy a Bossland's bot, anybody can sell his/her gold, so if everybody has the same level of knowledge about this business, the supply will go wild, and the price will drop to the point that you get only sh!t from what you're doing. That's what happen recently.
That's why he will not share his knowledge. He want to let Blizzard clean out the inexperienced ones, less cunning ones, less technology-savvy ones. Bossland gives you the tool, and you've paid for it. What's left is how you help yourself survive in this rat-race. This industry is no longer a game, it's already a millions business, so it's seriously competitive.
Bossland already did his job, and he did it well. The rest is yours.
