Rollyo is a very clever tool for limiting the sites you want to access on any given topic. It serves as a filter, if you will, of the sites you might want students to use when searching information for a topic of study. I like it a lot and know that I will use it next year. This seems relatively close to what I was thinking to do in Tag Bundles and Network Bundles in Thing #13. What are noteworthy differences in the tag bundles and Rollyo as far as students' investigations on any particular topic? Here is a link to my Rollyo: http://rollyo.com/linsleyi/kandels_fan/
