I don’t follow people who protect their tweets. If I do then it’s a mistake. I just don’t see the point in protecting tweets. Why would you want to? The best way to utilize the power of twitter is to be open. That is how you meet people here. That is how you meet outstanding educators here. That is how you learn through Twitter. That is how you become a better educator.
If you protect tweets then you are closing yourself off from the power of Twitter. You are closing yourself off from meeting outstanding educators. You are taking the safe road and refusing to grow. Worse, you are making it harder for people to discover who you are. Why are you afraid? Am I missing something?
