The social networking service App.net is quickly gaining popularity and Kiwi is one of the many apps you can use on your Mac to share your thoughts with other App.net subscribers. If you want to get your Kiwi action on outside of the app, you're in luck because now there are several add-on services that let you use its features in other Mac apps, too. Joe Workman has a github repository with services for Safari, LaunchBar, Quicksilver, Alfred, PopClip, Dropzone, and OS X Services, too. They're free to use, so you won't even have to break out your credit card.
