In Chapter 6 of his book, Will Richardson speaks to the power of combining our various social networks into a personalized learning network- in other words, using RSS feeds and social bookmarking to create an easy way of aggregating material relevant to your needs and interests. To be truthful, prior to this course, I hadn't used RSS much. However, I have used Delicious in the past to collect links for my students to use for research projects (I suppose I used this as kind of the "cheater's" way- instead of letting them find my own information, I provided them with more targeted searches). I can see a great potential in combining these two technologies, and certainly moreso in a school environment that is more technology-rich. Also, upon reading Richardson's description of Diigo, I am certainly excited about the possibility to use it to annotate webpages- this might provide an excellent way for me to model appropriate research and reading strategies for my students. It will certainly be a project to play with over my upcoming breaks.
