Aptly titled snapshot
These notes--terse, obscure, and endlessly self-referential--are all examples of a new phenomenon in social media called "microblogs": short electronic posts, sent to friends or to a more general community, that deliver some information about the sender. Sending microblogs broadcasts, "I am here!" Reading microblogs satisfies the craving of many people to know the smallest details of the lives of people in whom they are interested. Already, new-media intellectuals have coined a term to describe the new social behavior they say microblogging encourages: they talk of "presence," a shorthand for the idea that by using such tools, we can enjoy an "always on" virtual omnipresence.
