Deadsite 

1. A website that no longer exists or has been bought out by another user.

2. A popular website that once had a lot of traffic that now has little to no traffic due cultural, social changes, problems with the website's management or policies, etc.

Examples:

Herman: "Do you remember pets.com?"

Norman: "No."

Herman: "Me either. That is a real deadsite."

Mary: "If you want, we can chat on MySpace! I have an awesome page set up."

George: "You still use that piece of shit deadsite?"
