EdTech Magazine is a great, free website that has tons of articles, resources, product and service reviews, information and more about edtech topics and products. It is a great resource for any educator, educational technology specialist or director, or technology personnel.
I would have also included the following blogs in the list:
1. Cybrary Man's Educational Web Sites - Jerry has created a one-stop-find-everything resource for educational topics and edtech resources. If you can't find it here, it doesn't exist. Period.
2. Technology Tidbits: Thoughts of a Cyber-Hero - David Kapuler's blog is a great place to find tons of great educational resources and apps.
3. Connected Principals - a great blog for ideas and resources on edtech, and education, from an administrator's viewpoint.
4. Discovery Educator Network Blogs - great resource with links, ideas, resources and much more - not just on Discovery Education materials either.
Remember, if you weren't on this list and are an edtech blogger, don't worry. These lists, like all lists, are fun, great to be mentioned on, but don't mean your blog isn't an awesome resource too!
