Tyllendel's friend had an interesting reaction to the game when he first played it: he felt that all of the quest text was unbearable, and that he wanted to play the game rather than reading what NPCs told him. We've talked a little bit about this before -- obviously, when Blizzard kicked off WoW nearly five years ago, quest text was just the way quests were done, and while Blizzard has expanded the concept a bit since, it's still mostly the way MMOs work: you go to a character, talk to them, and they tell you where to go and what to do.
But I can see Tyl's friend's point: games are much less about telling these days and more about showing. You might understand how, if you've never played an MMO before, reading the quest text can take you right out of the game, rather than running off with an NPC or having the game show you rather than just tell you what to do. And Blizzard is getting there: later in the thread Slorkuz points out the recent Afrasiabi interview, and talks about how Alex mentions new ways of doing quests. For example, the quest team is trying to do a quest with no text, or direct players' attention without actually telling them, "look here." Text is the easiest and most basic way to help players accomplish goals, but as the game moves on, even the developers realize it's not the most elegant or immersive way to do it.
