Through a Tweet by Steven Anderson (follow him if you don’t) I learned about a great slide presentation created by Bethany Smith (another person you should follow on Twitter) about creating an online personal learning network (PLN). The presentation tells the story of how Bethany created her PLN before moving on to showing you how to create your own online PLN.
The presentation is embedded below.
