European Consitution in France: 2 unlinked competitive structures

(via), an interesting visualization of the impact of blogs and websites on the May poll about European Constitution in France. It's done by Franck Ghitalla and Guilhem Fouetillou from the "Université de Compiègne". Why do I blog this? it's interesting to see how the two 'sides' were structured as competitors: there are not so many links between both! Just few bottlenecks.
