Yeah, Habbo Hotel is not a good indicator of the Generation Z. In my time at high school, I have never heard any mention their "Habbo." A better indicator of kids using the internet would be...Facebook really.
Habbo Hotel isn't a social networking site as the article says, it's an obscure online game with no combat system (it's like an MMO Farmville I guess you could say). Another example would be Gaia Online.
They're both... ermmmm well at best they're poor representations of any generation.
