digg as aggregator

Who reads digg? As an aggregator, digg does not create content, but pulls it in from other sites that do the hard work. This makes for an interesting division between those who read digg first, and then go to the content with those who first read the content.
Digg is supposed to save me time by evaluating, via the wisdom of crowds, the quality/interest/value of articles on the internet. But I’d rather go straight to the source and find out for myself. My network is enough of third-party evaluation that I don’t actually have time for something like digg.
