Tip 2 - The City Guards are your friends - use them well.

This is kind of an adjunct to the whole "Read your Quest Journal" thing, but the other thing that clogs up the general chat channels is people asking for directions in the hub wow goldcities. Fortunately Blizzard has come up with a simple solution - just ask a city guard! They'll give you directions to everything in the city and even provide you with a little flag in your mini-map! You know, the employment situation in Azeroth must be pretty bad when you consider that most of these guards are level 75 or so and can easily wipe out virtually every monster in the game and they're taking the time out of their busy schedule to help you. The least you can do is avail yourself of their services. I don't even think they get paid!
