Web Logging is a good resource for teachers.  This program allows teachers to communicate away from school.  Students who don't feel comfortable speaking can blog and feel free to express themselves.  This resourse also can regulate what the students' can view.  The teacher can set up different links and have the students' view only those links.  I think feedback is important in any feild and this is a good tool to get feed back from your students.  It a good tool for getting feedback from your fellow teachers and sharing ideas to help the educational proceess of the students.
