As you may have heard, YouTube has been getting more social lately. Our activity feeds help your users stay up-to-date on the cool channels and videos that their friends (or anyone else, for that matter) have been uploading, subscribing to, adding as favorites and so forth.
But we don't just care about YouTube users. We also care about developers. And we want you to have time to be more social, too.
With that in mind, Jeff Fisher and I wrote a hands-on tutorial that explains how to build the YouTubeActivityViewer, a PHP application that uses the new activity feeds. The application uses our PHP client library with jQuery. If you're still not ready to rush out and socialize, you can also build in a caching system with memcache.
