Free Technology For Teachers is one of the most useful blogs I have ever seen. Within a week of checking it regularly, I had used the most recent Digital Storytelling post with the Anatomy and Physiology teacher and referred to the Diigo Teacher Acounts post for myself.
Beware, because it is high volume, and I have to be ruthless about what I explore further, what I pass on to teachers, and what I ignore entirely. You may also find the overuse of the word "awesome" somewhat distressing. However, I am in favor of any blog that reminds me of the existence of OK Go while stretching for an application to education at the same time.
