A clutch of interesting links on social networks from the weekend and Monday:

• Danah Boyd is academic about class-ism on Facebook and MySpace - summarized on BBC Online.
• Tom Murphy starts to hang with the kidz on Facebook. He has a point. And I just proved it for him.
• Plaxo and LinkedIn set off rather late. Perhaps too late?
• Facebook fanzine blog.
• Facing up to openness at Facebook.
• Predictions from Jeremiah.
