Last summer, I went to the National Association of Elementary School Principals conference in Baltimore and was exposed to people from throughout the country who know a lot more than I do about everything. As I listened to one keynote speaker (Todd Whitaker), he said, "If you are not on Twitter, you are missing out on a world of professional development that is very valuable to every Principal."
Well, I was on Twitter ... barely. So I decided to follow @toddwhitaker and a few others and now it has exploded. Each and every day (I try to check it at least one time a day and even "tweet" one time a day), I find articles and ideas that the staff at Slackwood are using immediately. It is the best professional development for educators that I have ever seen. You can find a community of like-minded people who are continually growing as professionals each time they tweet or read an article that has ideas and programs that are useful.
One of my people I follow says it like this, "Facebook is for people I know, Twitter if for people I wish I knew" @julnilsmith.
So, follow me on Twitter @JayBilly2.
