The web is becoming rich with great content; yet at the same rate that more websites there are providing good content, the more overwhelmingly difficult it is for people to keep up with them all. The answer to that are RSS feeds: so instead of people visiting a site to see what's new, feeds will send the content directly to them. What's also cool is that you are providing an API for other services to access you content in ways you never thought of. In this meeting we'll briefly talk about how RSS came to be, as well as the core language that RSS builds off of - XML. We'll check out how to construct an RSS feed ourselves, and then apply that knowledge towards creating a podcast. And if we have some time we'll look into some web services that take your RSS feed and do some awesome things to them.
