Toward a theory of “Assorted links”

Brad DeLong and Matt Yglesias, trendsetters of the blogosphere if there were any, are assembling "assorted links" once a day or so.  As do I and Yves Smith, not to mention the Herculean efforts of Mark Thoma.

Does anyone click on these things or do you simply wish to feel you have experienced a more comprehensive menu of what you have refused to learn?

A second-order question is whether or not I should care about the answer to the first query.
