contents	A Little Help from My Friends: Classroom 2.0 Educators Share Their Experiences Hargardon, Steve Educational Technology Profiles Social Networks Computer Mediated Communication Teacher Collaboration Computer Uses in Education Audiovisual Aids Internet Web Sites Blogs, wikis, podcasting, social networks... it seems the entire world has gone 2.0 crazy. 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. While these innovators range widely in their experience and comfort level with technology, every one's a part of Classroom 2.0 (classroom20.ning.com), a social network for educators exploring new technologies. Online, they have shared advice, technical know-how, and encouragement in a community where newbies should feel most welcome.
