Last week I blogged about how to start building a PLN, or personal learning network. Since then I have increased the number of folks I am following on Twitter and the number who are following me. But how to connect to these people? I was working on a project about RSS and aggregators and I was looking for a teacher to talk about how they used them. In my reviewing of the daily tweets, I noticed that @mbteach tweeted that Google Reader was one of her favorite Web 2.0 tools. I replied to her and asked if she would be willing to be part of my video. I did not think that this approach would produce anything, but I was testing the PLN waters. To my surprise, she was very willing to help. I had asked for a minute or less of video testimonial about how she uses Google Reader and its benefits. Within 12 hours, she uploaded a video to Youtube and sent me the link. She had created a 3 minute self-interview about Google Reader! Thanks Mary Beth! This experience has convinced me that there is more to Twitter than I had originally thought at the beginning of this course and that it is a viable means to sustain a PLN.
