Depends - sometimes I'm in the mood for grinding, most of the time I'm not.
If you *have* to grind to get somewhere, I don't like it.
Once played an MMO where there was not enough quests to effectively level up your character's two classes (one was fine, but doing the other class was really annoying, but it's something you really want to do for the shared abilities), and it made me quit the game.
Just not much fun in endlessly killing mobs for the sake of killing mobs.
