Scoop it provides a rich search field for my subjects of interest. I can search and subscribe to the work of other curators. I can easily 're-scoop' articles that fit my needs. I also troll for information on Facebook, Twitter, Google+, and many blogs. When I find an article that fits the needs of my students I use the handy Curation Widget to capture a summary of the article. If I'm being disciplined I also apply tags (keywords) to the articles that will help me when I'm teaching my classes.
