Are you at home and can I come over for a quick visit? Maybe you are busy. Let others’ know.
An app or a function in an existing social network like Facebook that lets you publish your status of your openness to surprise communication or a visit from your friends. Similar to instant messaging statuses, just for real life (you can call me, come over, busy, unavailable, etc.)
To find out and validate what your status really is.
Choose from a status scale (poor to rich, illiterate to polyhistor, pleb to king etc.), where you place yourself on it, and invite your friends to anonymously affirm your place in the hierarchy or place you somewhere else on the scale.
