Thread: Does anyone else feel that direct traffic from social bookmarking sites is worthless?

I'm talking about direct traffic here; not the traffic you'll inevitably get from increased link popularity. Whenever one of my websites gets posted on Reddit or Digg or Stumbleupon, I get a lot of visitors, but little to no ad revenue. I just feel as if the users of those websites are far too Internet-savvy to click on any adverts. Hell; a lot of them don't even get to see my ads as they have adblocker on. Anyone else find this particularly frustrating?
