Along with LizLawley, ClayShirky, DavidWeinberger, and RossMayfield, he writes / is an editor for the Corante weblog ManyToMany on SocialSoftware. He also contributes to the (French language) ConstellationW3 weblog on IT and society.
Although his papers can be found in scholary journals, he also publishes some of his research, e.g., Personal Knowledge Publishing and its Uses in Research, Oct. 2002 in his weblog, perhaps, because he believes that Scholarly journals are not where the interesting action is!
He maintains a list of blogging researchers at http://www2.iro.umontreal.ca/~paquetse/cgi-bin/om.cgi?Research_Blogs.
