Well, I play Everquest, and at the Rogue board in the non-EQ section there were a couple threads on this anime. Eventually, I sucked it up and went to take a look. Glad I did. Learned about One Piece the same way.

What was more surprising to me is that I already owned a couple issues of Shonen Jump, and I didn't even remember that both series were in the magazine when I started watching them. Couple weeks later I picked up one of them and looked at it again and went "Oh hey! Thats Naruto! And thats Luffy!"
