Curation tools were the one tools I didn't know fell into the category of Curation. During my graduate studies I used Diigo all the time. (I remember hearing about Delicious and thinking what the heck is that?). Diigo is still my go-to for organizing references and great websites.
Diigo is a great resource for students because they can bookmark their research sources and "carry" them from computer to computer. (Great for kids who tend to forget their flash drives).
For thing 6 I got hooked on Flipboard. I downloaded it on my iPhone and the iPad. What a cool tool! Love how you can customize your own personal magazine. I've added so many topics and I'm enjoying all of the things you can do on it. It is simple to use and can help students and professionals who are "new" to tech tools. Try it you will love it.
