This is not the correct way to think about the user experience
I'm wearing my glasses, and it honestly took me about 30 seconds of scanning to figure out which of those articles was an ad. Now think about the readwriteweb/facebook fiasco (http://www.readwriteweb.com/archives/facebook_wants_to_be_yo...) and consider how an average person interprets that page.
As much as I don't like digg, I think it is fair to say that the avg digg/reddit users are more tech savvy than facebook/myspace users. So this is not an equal comparison.
