In the advent of social networking, there are new mediums to help in job searching or bolstering your connections.
Web sites such as MySpace, Facebook, LinkedIn, Twitter, and Plaxo are great for reconnecting with ex-colleagues and classmates, while also keeping you abreast of industry goings-on and opportunities. Once you connect with people, you can see when their birthdays are and send them cards or learn when they've been promoted or found a new job and congratulate them.
