Hows it built?

I thought being part of the initial group of Digg users we were going to get some more behind the scenes of how Digg was being built. I know I was not as active on Circle so I might have missed previous posts/videos, but either way would love to see some more behind the scenes on the building of Digg. I am sure some of us geeks here would love to see the hardware and software stack behind Digg.
