Running daily quests

Running daily quests is a great way to make gold, especially for folks who have non-gathering professions or classes that don’t kill fast enough to make farming profitable.
The advantage of daily quests is three-fold:
1) completing them earns faction reputation, which usually provides high-level rewards,
2) they are a consistent way of earning a known amount of gold (and the gold earned is usually at a higher rate for the time invested in it), and
3) they are repeatable (obviously), so you can master the techniques needed to complete the quest quickly, and earn good gold (and rep rewards) over and over.
Technically there is a fourth advantage: many of the quests can be lumped together and done at the same time. This REALLY ups your gold-per-hour rate.
There is a new Daily Quest addon that tells you exactly how to complete each quest. It provides map waypoints to point you in the right direction, and it teaches you how to group the quests so you can run them concurrently.
If you find yourself either needing to farm up some reputation for a reward you’re after, or you just need good, consistent gold at level 80, you need this addon.
It literally puts a waypoint arrow on your screen when you select the dailies for a given zone (or for a given faction), and you simply follow the on-screen instructions. It is as close to automatic gold as you can get without using a bot.
