If you have not yet noticed, Digg has been down since earlier this morning. They have an “upgrade” message, which can be seen below, but this is a rather odd time to pull the site for upgrades. One would think yesterday would be the ideal time, less people are on the Internet on Sundays and even less when the Super Bowl is on. Hmm…. Where are the conspiracy theorists when I need them? What great new services could Digg be bringing us?
