There's a whole lot of gold making tips on this website, but they're all moot if you don't understand why it's important to be making all this gold in the first place! Making gold in WoW can be done in many different ways, and doesn't have to be a chore. It's incredibly rewarding, and the gold always comes in handy. Here's a few reasons why making gold in WoW should be something everyone spends at least a little bit of time on!
Reason #1: Making Gold Encourages Critical Thinking Skills
When you're raiding, your goal is to perform a "dance" while performing your DPS rotation (or healing/tanking.) On the auction house, success is based not on muscle memory but on mathematical reasoning, economics and logic. Learning how to profit by selling items on the WoW auction house may not pay in real money, but it pays in experience. Using the AH forces you to think critically, and can come in handy when working in real marketplaces such as eBay or Amazon.
Reason #2: Lots of Gold Sinks To Spend It On
Whether you've got your eye on a Sandstone Drake, Mekgineer's Chopper, Traveler's Tundra Mammoth, or still need to save up for epic flying, having a regular supply of gold from the auction house can make it happen. Mists of Pandaria will bring even more gold sinks; new mounts, and the Black Market auction house. Stocking up on items to sell when MoP hits can give you the gold you need to purchase these items when they become available!
Reason #3: Being Gold Capped Is Its Own Kind of Achievement
Reaching the gold cap of 999,999g is no easy task, but can be incredibly rewarding. There isn't currently an achievement for this, but seeing your gold total reach the cap is a satisfying experience! It takes a lot of dedication to amass one million gold. WarcraftEcon.com has a Hall of Fame for players who have reached this milestone, as well as other significant gold making milestones. If a million gold seems daunting, set your own goal! Whether it's 1,000g, 10,000g, or 100,000g, it's rewarding to set goals and reach them. As you become more experienced in making gold, the gold cap might end up not being too far away!
