Aha! We've both noticed a form of social media "gaming." I'm writing about this for a presentation as I write this response. It's Auto-retweeting that's to blame.
I post at Social Media Today about once a week. I've written some posts that have gone ballistic ("Delete Your Klout Profile Now!") and many more that gather less than 1,000 page views.
After a post of mine goes up I'll check back an hour or two later to see how it's doing. Usually there are 150-200 page views. BUT at precisely that same moment there are 125-150 re-tweets.
If all these re-tweets come from people who've actually read the post and been impressed enough to re-tweet it, that would mean almost 90% of the readers were passing it along--which is absurd.
A few days later things simmer down and I end up with 1,000 views and about 200 re-tweets in total. When I analyze the progress of the post on Topsy I can see some RT's of RT's, but a substantial majority are people re-tweeting the post directly from the Social Media Today feed on Twitter.
What's happening is either automated or hand processed auto-RTs--a tweet goes out on the Social Media Today feed on Twitter (with more than 100,000 followers) Some people immediately re-tweet the SMT tweet without reading the article because they want to raise the quality of their own Twitter feed. That's it. SMT tweets, they re-tweet. As a result there's a RT but no page view on SMT.
These people, I believe, look for a few dozen sources of high quality material like SMT and every single time a post is released, they immediately re-tweet the post. I can find people who post 50-100 times a day. Even if these people did nothing but sit in front of their computer all day hunting for material they couldn't possibly read, evaluate, and then re-tweet that number of links.
A recent article in AdAge by Jack Krawczyk, and Jon Steinberg looked at articles passed along via BuzzFeed and StumbledUpon and found that the average number of people who visit an article based on a recommendation by another person is only nine people. Real viral pass-along influence happens in very small numbers between people who know each other.
Brian Solis probably gets huge pass along traffic numbers from people who actually read his content. But as you note (and my own observations confirm) there are a lot of people out there who are re-tweeting without reading just for the sake of improving the quality of their Twitter feed.
It's the "I'm A Genius By Association" effect.
