A menubar app with a system-wide, user-configurable hotkey that allows simultaneous posting of a "mood" to iChat, Skype, Adium, Twitter, Jaiku, Tumblr and Facebook, or any combination of these services.
Keywords preceded by "@", "!" or "%" allow for special functions such as current weather, current iTunes track, current Time (+x minutes) and other functions to be inserted. URL's are automatically shortened using Metamark.
MoodBlast is built on a combination of Cocoa and Applescript, and can be navigated by keyboard commands alone, or used with a mouse and keyboard.
