Why are you participating in 23 Things? What do you hope to learn? How does writing on the Internet, knowing anyone could read it, change how you write or feel about writing?
The first reason I am participating in 23 things is I am in need of Sb-Ceus to continue my certification. The second reason I am in 23 things is that there is so much more to the internet than I am aware. I know how to locate various tibits of information, I can use twitter, and I understand the therories behind Facebook. Yet there is much more floating around in cyberspace that could and can make me a more efficient teacher or more efficient in my day to day life.
Writing on the internet doesn't really bother me all that much. It is easier to write than to stand in front of a group of 300 to 400 people and give a lecture. However, I will need to proofread a little better prior to submitting.
