Wouldn't it be great if you could send a tweet via Notification Center's "Click to Tweet" feature without needing to take your hands off of the keyboard? Apparently Stack Exchange user Ewwis thought so, too, and he wrote up a nice little AppleScript to do so. Macworld's Kirk McElhearn, who is a fan of AppleScripting and shortcuts, highlighted this script this morning.
Just copy, paste and save the script below, launch it with a keyboard shortcut with LaunchBar or another similar utility, and you'll be tweeting in an instant.
