Slashdot Effect

I often wonder what it would be like to have a site like Slashdot. For those that don't know, Slashdot is basically a site for nerds with links to various nerdy articles on the net, and it then allows you to comment on these articles. Sorta like an organized Usenet discussion. The thing is that they get amazing traffic for a "personal" site. 1/2 million hits a day. They also overload other servers with the "Slashdot Effect". Basically when they put a link up to a story, everyone will try to visit that site and read it, thus taking down servers that can't handle the load. It's gotta be more than a full time job to run Slashdot. I can only imagine.
