As the popularity of blogs grew, so did the popularity of another technology, called a feed or RSS feed. Both of these terms refer to the same thing. Feeds are content that is pushed out to registered users who have signed up to receive them. The content that’s pushed out can be short teasers about blog posts, news, or podcasts or it can be a complete blog post, news item, or article.
Podcasts can’t be pushed out through RSS, but you can send a teaser or blurb about the podcast. (And, if you think podcasts have something to do with the pod people from Invasion of the Body Snatchers, have I got news for you: A podcast is actually an audio recording that’s available to listen to online. It’s an audio version of an article, news story, or blog post.)
