PLNs are learning opportunities that provide a way to move from professional development as a special event, such as a workshop or a once a year conference to “a continuous flow of learning” (Guhlin, 2009). There are many ways to develop a PLN, and many interactive and collaborative tools to use including twitter, nings, social networks, blogs, and social bookmarking sites like Diigo. A PLN becomes a “dedicated learning environment [which] is unique to each individual” and its efficacy depends on how much or how little you chose to share and learn from other individuals in your PLN (Kapuler, 2009).
