Thanks for sharing your experience. I was approached by our administrator and asked to do a little blog evangelism.
I agree with your approach of demoing what you are doing, showing what you are up to as a model of what blogging can be used for. I think I will be approaching in the same way, just showing what myself and my class are up to.
From what I have heard and seen, the numbers thing is typical. There seems to be a small response across platform from teachers, who seem to be reluctant to dabble in the blogosphere. I, too, thought I had converted a colleague, but he seems to have stalled at one post. I mentioned to him about what I am doing with blogs and my lit class , and the lit team blog and he actually sounded interested, so I am going to continue trying to promote this platform.
Thanks for the post.
