John Highland has a quick tutorial showing how to create a lifestream with PHP out of all of the RSS feeds surrounding the multiple social networking and blogging sites you have out there (with the help of SimplePie).

Its not secret, I love social networking, I cant get enough of it. I also love programming and anything internet related. I'm not sure how I came across it, but a PHP based, Object Oriented RSS caching tool named SimplePie caught my attention.

SimplePie offers one piece of functionality that he found particularly useful - the ability to merge RSS feeds easily. He took advantage of the ability and pulled together his Twitter, Flickr, Pownce, Digg and Youtube RSS feeds to make one mega-feed. You can see an example of it in action over on his personal site.
