I have been fascinated to read the many blogs my colleagues have been writing....so interesting.
I agree with Vickie Davis AKA "Cool Cat Teacher" that it is important and very nice to write and receive meaningful comments. I am not good at making comments. I guess I worry my comment might be lame or dumb. I am learning and trying to be bolder. Actually Facebook has helped me realize that it is not necessary to write long comments. The important thing is to be thoughtful.
