I have personally experienced the power of forming a PLN using Twitter. It will transform the way you view PD. However, I want to point out that Twitter is also a powerful tool for students to connect with teachers and experts!
If you haven't started using Twitter -- do not fret. You can lurk on Twitter to get the hang of it before starting to add to the conversation. When you do start contributing you will be amazed at the results!
