What is the "silk road" and what does it have to do with bitcoin? I have read a lot about the silk road and I am still unsure what it is. I went to http://silkroadmarket.org but it just says that the site is down.
Silkroad is an anonymous online marketplace inside the Tor network which became famous for selling illegal drugs.

They don't have anything to do with the Bitcoin project, except for the fact that they accept bitcoins as a payment method.
