Is that like "Comment", "No Comment"?

here are some interesting overlaps, and distinctions,

"Interesting" but you don't say why you think so?

I just imagine the teenager-in-the-basement user and his interests.

This is much more obvious in the news.yahoo.com
Most Popular lists for the pictures and viewed.
A political group has skewed these trash results in Yahoo/news' Most Recommended category.

And then there are the internationals.

Does the P-I able to show a difference from
in-state, out-of-state, international readers/viewers?

And why is this blog not featured on the 'home page' of the P-I?

Sorry, my thoughts on what made the lists "interesting" got lost somewhere in the drafting stage.

It's unusual for the two lists to share half their items, for one thing. As a general rule of thumb, many of the stories that people choose to read -- especially sports and crime stories -- often are not the ones that they end up passing along to other people they know.

On the other hand, the stories that are unique to the "most e-mailed" list -- such as stunning results from a WSU study on toxins, extreme croquet and the "No Stud" drywall hanger -- give some hints about what readers find valuable and/or fascinating enough to pass along. Chilling, fun and useful sums up those three.

To answer your other questions: No, we can't reliably tell where users are coming from within the United States since in many cases the only data we have to work from are users' IP addresses.
