The article “Art and the API” by Jer Thorp describes an API (Application Programming Interface) as a conduit or a connection which can bridge or transform data from one source to some other place.
IFTTT provides a service or system where you select two API’s and connect them with some simple rules. I like the simplicity of the idea and that it can expand into a large system where you could possibly have all your social feeds documented in a google doc.
The two are comparable in that IFTTT is a work that just bridges connections between APIs.
My formula adds the name and information of any new follower on twitter to a google doc.
