As an ex-Digger, I can tell you that it was Digg that killed Digg for me. At one point in time, Digg was cool. Granted, it was still mostly a rehash of news from Reddit, 4Chan and other sites, but the audience base was large enough to provide original content as well, and the UI was considerably better than any of the other sites.
What killed it (for me anyway) was that Digg suddenly allowed advertisers to start posting away. Ads popped up everywhere, and every other post from directly from Mashable. Digg was no longer cool, and mostly, it was Mashable's alternative site. :)
I switched to Reddit. Reddit didn't like all the Digg users migrating over initially, but attitudes have cooled over time. I can't really see a move that Digg could make at this point that would entice me back.
