Just finished the final touches on a new Facebook application I entitled, "Status Last 10."
In a nutshell, the app displays a list of your last ten status messages that you entered into Facebook. You can display the list on your Wall or Boxes Tab. Much of the blogoshpere speculates that Facebook opened their status API to compete with Twitter.
In any event, the app is coded in PHP. The next step will be to show the code once I get the refactorings completed and share the discoveries. More to come once I get the time.
