I've written a few blog posts on my own website about possible uses of Ifttt.com. Ifttt allows you to set up a trigger from one web application (eg A Google News search for “libraries”), so that it triggers an action in another web application any time this happens (eg Creates a blog post from any newspaper articles it finds and links to the full news article). Each trigger/action you set up is called a task.

The blog posts I've put together so far are:

Using ifttt for productivity and more: How I've used the service to pull together tasks I need to do and show that I have been productive.

It's raining - Twitter says get to the library: Creating triggers based on the weather to encourage use of the library.

Pulling photo storage together with ifttt: Ensuring that photographs I've uploaded to various photo-sharing sites are all stored automatically in Flickr as well.
