This week's lesson on social networking provides additional tools for keeping in contact with people. It can be used like an online resume for future employers and for friends to find each other after long periods of time. In addition, I think this process would be valuable when participating in online learning activities by using people rather than print materials as resources.
I did create a profile on Linkedin. I'd need to spend a lot more time to customize my information to make it very useful. I did attempt to search some past colleagues, but no one was listed. We'll see what happens in the future.
