How can I disable the tweet sound when using Click to Tweet in Notification Center? I really like being able to send tweets on Twitter from Notification Center, but I can live without the sound that plays when you click Send. Is there a way to disable or customize the tweet sound?
The "tweet sent" sound file is located at

/System/Library/SocialServices/Twitter.socialplugin/Contents/Resources/TwitterSent.caf


If you remove or change that file, then the sound should change accordingly.
