24o’clocks is an application for Twitter that allows you to survey your Twitter life or the Twitter life of anyone else that you are interested in. To try out the service, just enter the Twitter username that you are interested in and see an hour-by-hour display of every tweet that person has made that day. You can also click back to see the full history of that user’s tweets, basically giving you a full account of someone’s tweets in calendar format. No registration is required to use 24o’clocks, and along with the person’s tweets, their current photo will also be displayed to the left of the calendar.
