The content in this podcast does not need any justifying for it's importance, relevance, or thoughtfulness. I mean, it's selections the editors of The Economist deliberately picked! The only drawback is that it doesn't provide the depth of coverage the print or web edition does, hence "Editor's Highlights." But it is great start to filter through the print or web edition for articles relating to one's interest.
I also like how the weekly podcast is available as one download (with six articles in one file), and as each highlight as a separate file. This allows me to manage the content easier (I just play the one file with everything). But with individual files per highlight, I can suggest specific portions to people without having to share the entire week's work. -- Speaking of, where's Feb 17's full file?
(BTW, I'm not an idiot, so I realize why these are just quick highlights. And it does it's job well, because I usually end up at the economist's website exploring at least one highlight they mention each week.)
