But it's not NEW!

Without fail, whenever there's a new buzzword/concept/idea getting a lot of attention, there's a chorus of offended geeks who have seen it all before. They can't see that a subtle technological difference may be a significant user-experience difference, and that makes all the difference in the world. This comment is the perfect example:
Podcast this, podcast that. It's just streaming audio for god's sakes! It's not some strictly iPod-related technology, it's not new technology by any stretch of the imagination, and it's not a new compression scheme either. I don't see what the big deal is.
And Leslie has the perfect response.
