I recommend this story because it takes a step back from all of the vitriol surrounding the recent changes to Facebook's privacy settings in order to provide some perspective. I especially liked the comparison of Twitter vs. Facebook in terms of "joining" a public vs. "creating" a public.

This story does not have enough context. It begs the question: If Blacks are slightly over represented in terms their numbers compared to the general population, what segment of our population is under represented?

The writer misses the point, I don't want unity for unity's sake! I want the type of unity it takes for partisans to stop sniping at each other long enough to put their heads together and work out real solutions to real problems. Politics has become a contest where the participants will do anything to win. Republicans and Democrats need to answer this question honestly: Is it more important to win the next national election or more important to do the right thing for the United States of America?

MM is more of a columinst than a journalist. Her writing tends to argue for or against something. As a result she tends to include facts that support her argument, and omit those that don't. There's nothing wrong with that but, it's not "news", it's "opinion".

This article leaves me wanting for more information. For example, it mentions "looters" twice in the sidebar text but, does not say if, or how, the new site is being protected from looters. Also, there are no statements or quotes from the Peruvian government or academic instituions. I would have liked to know more about how subsequent exploration and examination of these ruins will be funded. In the last paragraph, the "plug" for the US cable TV channel is blatent, and adds little value to the story.
