The appeal of all of this is the immediacy and portability. Because microposts are so brief (typically 140 � 200 characters), a microblogger can update his or her microblog often enough to keep readers informed as to whatever they're doing (commonly known as twittering).

One such application, for example, a mash-up with Google Maps called Twittervision, shows users the geographical location of posters. Hey, GFI!
