Beware that this tutorial is slightly unmaintained. Images are lost thanks to my hosting provider, and my own lifestream has since been changed to work with a Symfony backend. To understand Yahoo Pipes though, the text can still provide a good insight.
So, as you might have noticed I build my own little copy of a Lifestream, much like Jeremy Keith (Adactio) did on his website. Although it is fun to build a lifestream, it isn’t the simplest thing to do, so I took a different approach to use mine and build one using Yahoo Pipes.
