The Finger Protocol is a simple network protocol “for the exchange of human-oriented status and user information”. Back when most organizations had only one computer (likely a Unix mainframe) on which everyone had their own account, the Finger Protocol would be used to display information about those working at the organization (what they were working on, contact information, etc.). Nowadays, although some groups may continue to use it for that purpose, it’s mainly used by small internet enthusiasts such as myself as a way to share basic contact information and what’s going on in our lives.

You can finger(1) me using a browser which supports the protocol (such as Lagrange) at finger:// or by specifying finger on the command line.
