I like the concept of creating an extended online community. I believe that one of the best ways for teachers to become better teachers is to interact and share ideas with each other. I know that in my career, my best lessons have been born during collaboration. Good lessons can become great lessons with critique and new ideas from other teachers. I have no issue with sharing my ideas online.
I am glad to have finally set up Google Reader. I am looking forward to adding subscriptions to some of my favorite websites. I really like the idea that the information I like on the web comes to me in one place rather than me having to go tons of different websites. It was really easy to set up too. One blog that I subscribed to is the "Social Studies and History Teacher's Blog" at http://multimedialearningllc.wordpress.com/.
