Interesting development that could drive the simple idea further, or even combine them as mini services to create 'skills'. I have used IFTTT for some time as part of Echo voice commands. Yet to see an example of this.

Now, as part of the company’s bid to grow in ubiquity, it is taking the next natural step: instead of expecting users to find or write those recipes themselves on IFTTT, it will now allow developer partners to embed those IFTTT recipes directly in their own third-party apps. ...

I also point out what seems to be a competitor to IFTTT, Microsoft Flow.
