How Educators might use blogs?

Educators could have many uses for blogs.  Blogs could be a means of keeping in touch or networking.  It could also be means of passing information along to help solve problems that they might be encountering.  It can be a valuable tool this way.  Educators and Administrators both could post problems they've had and solutions that might have worked for them are even ones that did not work.  Blogging could create a network of valuable information being passed back in forth from many people and many places to help all people reading grow in their experience and knowledge.
