Among the followers are educators, who, in ever increasing numbers, are integrating these online, interactive tools into their classrooms and even libraries. This article presents profiles of a few of educators who have taken the plunge, launching blogs, signing on to social networks, and stepping up to the podcast mic in order to create innovative learning opportunities that encourage collaboration as never before. The profiles are: (1) Nancy Bosch on Blogs; (2) Ginger Lewman on Social Networking; (3) Dr. Tom Stiff, Susan Stiff, Diane Hammond, Dr. Steve MacLean on Blogs; (4) Carolyn Foote on Wikis; (5) Lisa Parisi on Podcasts; (6) Dave Ehrhart on Social Bookmarking; and (7) Barbara Barreda on All.
