I've just started trying out IFTTT. Partly this is because the Feedburner feed for this blog has needed manually prompting to update my Twitter feed, but also because I'm investigating using it to post automatically to Blogger on behalf of my friends at Speculative Grammarian.
To do this, I'm using a feed from one of my Google Code projects. It's a semantic recommendation system I've been working on. I call it Emily, because it finds things (or at least, it will do when it's up and running). Code updates from the project should be appearing here.
