Good question.  Not that I know of.  

The closest thing that I know about is this work: 

Robert West, Ingmar Weber, and Carlos Castillo. 2012. Drawing a data-driven portrait of Wikipedia editors. WikiSym '12. ACM, New York, NY, USA, , Article 3 , 10 pages. DOI: 10.1145/2462932.2462937

http://www.wikisym.org/ws2012/p1wikisym2012.pdf

It was done using a browser toolbar to correlate Wikipedian editing patterns with other browsing behavior.

Wonderful.  Is there anything similar for reader sessions?
