Learning networks in previous decades were insular groups formed around academic journals, learned societies, and professional conferences. Today, galaxies of students, academics, professionals, and amateurs are using blogs, wikis, presentation tools like Slideshare, YouTube videos, and e-mail lists to collaborate, pursue, and present knowledge in any discipline. All are supported by, yet independent of, universities, other cultural and government institutions, and private companies, not to mention hours of volunteered time by enthusiasts.
