What it really means
Funny how something gets repackaged and then becomes a fad. Prediction: podcasts are going nowhere. Maddox put it best when he said:
“Podcast: Someone had the revolutionary idea of taking a compressed audio file and putting it online. Yeah, doesn’t sound so sexy when I describe it for what it is, does it? It would have been a great idea if streaming audio wasn’t already around for over a decade before the word “podcast” entered the lexicon.
Podcasting: It’s snob for “streaming audio.”

Really though, it’s the same thing as blogs. Blogs are basically websites repackaged. I think though when ever something becomes extremely mainstream new words pop up to decribe it.
