The "Stickiest" Law Prof Blogs

Following up on yesterday's post, Law Prof Blog Rankings:  as others have pointed out, raw traffic numbers (visitors and page views) are only one of the measures of the influence of blogs.  "Stickiness' -- the amount of time readers spend on a blog -- also is an important metric.  Unfortunately, the SiteMeter measure -- Average Visit Length -- is problematic for at least two reasons.  First, it computes the average only for the most recent week.  Second, it begins counting the visit length only when a reader goes to a second page; if a reader stays on a single page, the visit is given a 0 visit length (no matter how long the reader lingers on that page).

From what I am told, Alexa uses a more sophisticated aproach in computing its Time on Site metric, which it measures over rolling weekly, monthly, and three-month periods.  Here are the three-month Time on Site data for the 25 of the Top 35 Law Prof blogs by traffic as measured by Alexa:
