The Daily Grind: Which MMO has the best economy?

I'm an incurable trader and merchant, maybe even more than I'm a crafter, so I'm forever droning on about the good ol' days in long-gone sandboxes where players, not raid bosses, delivered all the objects used in the world. Making stuff is great, and lots of MMOs, even themeparks, have that, but I also I like setting up shops, trading on auction halls, finding great deals, and knowing just when to buy low to sell high, which isn't always the type of creative PvP gameplay that modern MMORPGs enable, let alone embrace.

But you can't trade in long-gone sandboxes, either, so today I want to tap the collective wisdom of the Massively readers: Which MMO has the most vibrant crafting and trading economy, right now, in a legally playable and living MMO? Specifically, where's the best MMO to truly be a player merchant?

Every morning, the Massively bloggers probe the minds of their readers with deep, thought-provoking questions about that most serious of topics: massively online gaming. We crave your opinions, so grab your caffeinated beverage of choice and chime in on today's Daily Grind!
