One of such feature is a Space Time Map you may use to navigate into the dimensions of space (into the map surface) and in time (selecting the time window on which you want to look into the map).
To locate a point on a Space Time map you need a location and a time reference associated to any meaningful Social Network action Goose can read out of your Social Network channels related to you and your friends. A geo-localized Post or Tweet, a Check-In, a geo-referenced image coming from your Social Network feeds can be allocated onto a Space Time Map.
