Everyone does know everything, if they have a desire to. The knowledge is floating around on the internet - are you upset that you're a newbie w/ respect to the Totemic quests? Check allas. Raid strat? google it, or ask your guildies who have.

That's more what is meant by "everyone knows everything." Most of the knowledge is confirmable with ease, and someone surely knows so if you want to know something you can.
