Lol if Skiierman thinks the only thing 4chan does is DDoS sites it doesn't like. The real Anons were the ones who crashed Paypal, Skype, stole Sarah Palin's email info, run Tor network, and smuggle rootkits and proxy programs across the world. Yes. That was all anonymous (with the exception of rootkits now being produced and sold by the russian mafia).
Bigger impact than you think that you never hear about.
