Starting out in game WoW gold is not that important. Lets face it levels 1 - 10 all your doing anyways is getting your class training done mainly, secondly your profession training. Some people play this way and others buy weapons and armor from vendor, personally I think that is a waste of time. As you quest weapons and armor will fall that you can use. Some quest will reward you with decent armor and weapons as well.
As you level gold will become more important. Not just to satisfy some silly wants, but to make sure your needs are met in game. Ever since the new patch came out, lower level characters have been able to buy their first mount at level 30 instead of 40. This will cause more of a strain on low levels to get the gold needed for their first mount. There are many ways to make gold in WoW, however at low level you will not be able to do all of them.
The fact of the matter though is this, to train your characters class and professions you are going to need gold eventually, it will not always be cheap, higher level gets more expensive. There also is the issue of using flight paths, although they are not expensive by any means, starting out you are going to want to have some silver and copper to fly to wherever it is you are going. Mounts are another thing, level 30, 60 and 70 you can get mounts. Trust me mounts making questing a lot easier.
My pricing may be off slightly, but this is roughly the cost of mounts as you level.
Lots of things can get costly. A simple upgrade, maybe a new weapon, perhaps you want to play around with fireworks and other fun items. Even your repair bill to the Blacksmith is going to get even more costly. Eventually you may want potions and elixirs or the best enchants. It all cost gold. So this site is here to help you in the direction of getting more gold and getting the things you want.
