I joined Twitter on February 25, 2009, so I just celebrated my one year anniversary. (You can find out when you Twitter here.) My participation on this social networking sight has truly transformed my life. I use Twitter via Tweetdeck everyday on my laptop or iPhone. I have a tremendous PLN (personal learning network) that shares great resources, answers questions, points me toward great posts and articles, and lets me know how to join the conversation at conferences virtually. My PLN also “pats me on the back” when things are going well and helps me work out the bumps in the road when things aren’t going so well. They encourage me, challenge me, and support me in my use of technology within my classroom.
