Richard MacManus has a great rundown of digg trends. His findings...
* The top diggers have the best chance at getting a story on the home page
* Digg users also have their favored blogs and websites, which get a disproportionate amount of attention than other less fortunate sites
* Sunday is the least active day and Thursday the most active
* The percentage of submitted stories that make it to the digg homepage during the week is around 15-19%
