People and organizations start using Twitter today for general public announcements or as a primary communication channel in closed communities. For example, I use Twitter when I want to share a story with my students or announce a newly available studying material. But what do you do if there are some people who do not want to use Twitter and still rely on email communication? By using Twitter API and Google AppsScript you can write and run a simple mashup that sends an email anytime you post a new message on Twitter.
As a developer, you can figure out how to make your program connect to Facebook, Twitter, SMS, and Email. Or you can use the Embarke API and connect just to Embarke, a messaging platform that connects you to them all. You can skip learning the specifics of how to connect to each of them. The REST API's website has a five minute tutorial video on how to use this gateway to its developer tools for social communications.
