Personally, I'm an avid user of many different platforms for bookmarking. Pinterest is a platform that is easily accessible and many feel comfortable with. I am also very comfortable using Diigo, Delicious, and others. Each are excellent resources and have been a huge benefit to me. On occasion however, I sill find that I may need to use a function that I am a novice at, or a colleague wants to use a different sharing platform. No need to panic - I've got my trusty Web 2.0 quick guide, which can help me sort out the new tool in a snap.
Each chapter thoroughly explains what the tool is, advantages of using the tool, ways to incorporate it into education, detailed pictures guiding you through getting started, and references.
