I think you should point all the out, because I do not share your opinion about this. World of Warcraft is completely different from any other social network. I do not say they are not the same. They have several similar things, like meeting new people, and more, but in the MMORPGS and any other MMO game, the main point to play the game and advance through it. Only after that comes the social and friendship stuff. The comparison would take too much time to finish and the space and time are always limited. MySpace is great for meeting new people, as the World of Warcraft is great for playing.
