Wikileaks is under a mass ddos attack right now. Try to visit the site... I am unable to.
The principle for a lot of people is watch or listen before buying. I can't tell you how much money piracy has saved me. I buy movies, music, and games... however I always try the product before I buy it.
EDIT: Apparently Wikileaks is supposed to drop those new US documents tomorrow. The Guardian, Der Spiegel and NYT have it. They said they will still run the story even if Wikileaks is still down... Here is a theory. The US gov is trying to shut down piracy websites (Mostly torrent sites) to stop the information from spreading... Ill be you $10
