I am beginning to understand how a PLN can be useful in the classroom, co-workers, and visitors. The PLN helps us connect to people around us and get more information and new ideas! I enjoyed commenting and reading others posts and like that I can share my thoughts with others. I downloaded the Diigo to my computer and Google chrome. I can't believe how far technology has come to where I can save information from my computer and open it from a completely different location. Amazing!
