If you are a professional, you should have a PLN. Your PLN (personal or professional learning network) is the community of people you interact with and learn from on a regular basis. They may be people you meet on a daily basis, but more often than not in the digital age, many PLNs are comprised of people we interact with on social networking sites. In my opinion, the most powerful PLN building tool is Twitter. For me, Twitter is an incredibly powerful yet simple tool that enables me to connect with, and learn from, specialists, experts and enthusiasts in my chosen field of expertise. Put simply, I follow teachers, learning professionals and education experts from all around the world - over 1400 at my last count. I learn something new everyday, usually as a result of dialogue on Twitter, or clicking on a link someone has shared in my timeline.
