Gosh, a new blog post, will wonders never cease?
NNWInstaPost looks at what you are reading in NetNewsWire whether in the regular or tab view, sorts out your username/password stuff so you don't have to worry, and does a Growl post when it's all over. Nice and easy. You could even trigger NNWInstaPost from a keyboard shortcut if you were feeling very brave
