“IFTTT, if you’re unfamiliar, is a utility that you can use to hook multiple web services together to perform automated actions for you. Want a text message every time you get an email from a friend? Care to have your photos automatically shipped off to SkyDrive or Dropbox or Flickr as they’re shot? There’s a ton more stuff that you can do with the hundreds of channels that support popular apps, services and actions.“
IFTTT is one of my favourite web services of the past year, capable of creating dozens of useful tools, and a great illustration of why open APIs are important and powerful.
