Do Diggers actually read the articles they’re digging or burying?

Over at Slashdot, it’s pretty common for people to comment on a story without having actually looked at any of the pages the story summary links to, let alone read the summary itself. Now I’m not overly familiar with Digg, but I do hear an awful lot about that site. A few of my articles have been submitted there. In any case, I was wondering, do the people at Digg, in general, tend to read the articles they are digging or burying? Or do they blindly dig and bury based on the article title and summary?
