Microsoft has tried in the past to make apps communicate, like with Object Linking and Embedding (OLE) in the 1990s. It worked, but in a limited fashion, allowing for linking data between Word and Excel. But if you wanted to share data from non-Microsoft apps, you were out of luck.
Now, however, Microsoft has come out with a service (it’s not right to call it an app) called Flow, which brings the If This Then That (IFTTT) functionality of the Web to desktop apps. IFTTT is a feature for Web services that generates actions based on conditions. It’s how Twitter informs you when someone follows you, likes your tweet or responds to your tweet, for example.
