Thing 17 (Discovering Delicious)

Social bookmarking is a great tool for searching for information.  The saves (Delicious), diggs (DIGG), and likes (StumbleUpon) helps to give you sites/blogs that are popular and therefore more likely to be useful.  Seeing other people's tags helps to give you ideas on how to zero in on the exact topic you are looking for.  As a teacher, being able to easily look up reliable resources for teaching a lesson or assigning a project on a very specific topic will be not only helpful, but I can see it motivating me to look for more examples of technology based methods to teach.
