Threat Discussion : World of Warcraft General Discussions

Could someone point me to a good discussion on threat? I understand the basic premis but would like to read an in depth discussion on it. Also looking for any direction for tanking guides for warriors and how their threat generation works specifically. If you have any resources you could direct me to that would be great.

Get a threat meter addon =D Look up like threatmeter on umm curse-gaming.com or net or w/e

For tanking just sunder a couple of times and use revenge and any other moves that say "generate high amount of threat or w/e"
