Use twitter? Use a command launcher app like SlickRun or Launchy? Well here’s a handy URL to make a command to quickly post an update.
If using SlickRun: http://twitter.com/home?status=$W$
$W$ means to put parameters URL encoded there. I’ve it mapped to a magicword of “tweet” so can send an update in SlickRun with: tweet wuzzup world!
See it in action:
