Slides (with embedded videos) from a presentation I gave for librarians of the UNC Library, organized by the Staff Development Committee, on December 4th, 2009. I covered Dropbox, Twitter, and Google Wave, and in the process talked about broader trends such as cloud computing and social networking, and what they (might) mean for libraries. A lot of what I actually said is left out here, so until I create an audio track (if I ever do), please contact me if you have questions or are curious.
