“If the Internet was once ungoverned by etiquette, those days are gone; MySpace and its siblings, by many accounts the future of the Net, are rife with discussions of good manners versus unforgivable faux pas. There isn’t an aristocratic class, just yet, but you can see the lines forming in the sand, renegades and bad boys posting bulletins pell-mell, uploading risque pictures, collecting “friends” as if it’s all some big popularity contest — while mannered netizens look on disapprovingly. Screw up and you just might get dumped, online and off.”
