I hope yo all know what RSS is, its simple (even very simple) but it is some how difficult to explain, although many of us use RSS even without knowing.
I will skip all the explanation, you can read about it in Wikipedia, but if you are reading my stuff here, then you already know what blog is, and this blog also have its own RSS feed, and it means you can subscribe to the feed and get the updates on regular basis (whenever its published) and it is the same concept for video RSS channel, only that you get video content and not only text or pictures. The feed for this blog is here, and when you open is using any RSS reader like Google reader, you will see each entry and will be able to receive updates easily, try it.
