Podcasting in classroom

http://www.npr.org/templates/story/story.php?storyId=97511513
This is a podcast about a group of people commonly known as vegans have such a dilemma on Thanksgiving Day, other known as Turkey's Day. The report is interesting that on a special holiday that you supposed to eat special food to celebrate but due to your eating habit or moral awareness that eating animals are not acceptable, you cannot enjoy the holiday feast with your family. If you do plan to eat turkey on Thanksgiving, then you cannot call yourself as a vegan. Or cited from this report, partial vegan is flexitarian.
While I was digging from cites to cites of podcasts, I was trying to find ones that with learning value and are learnable to students. In other words, my judgements of whether a podcast is suitable to my classroom, are based on its practicality, authenticity, and the language proficiency of its target listeners. The reason why I post about this podcast are that comparing to most other ESL podcasts,

1. it has a script but not word by word print version of the podcasting. It is rather, to some extent, a paraphrase of the original podcasting.
2. its topic is culture-related, not only historically, but also contemporarily.
3. it is in a form of news report, which is authentic using of English: normal speed of talking, daily vocabulary and grammar.
4. it offers a downloadable mp3 file, which you can save it for later study.

Well, it is not practical to use podcasting in my classroom where I still think the traditional teaching and learning procedure should take place, instead of e-learning, which I suppose, should happen at home, office, or on bus, train, etc., where you have leisure time and passion to learn besides school time. Whereas, I totally agree with the idea of web2.0 classroom. "In the world of learning, what this[ubiquitous computing] means is having learning available no matter what you are doing."

Where and when the school and time that can be spend in school is not available or vacant, one can benefit from sharing information online as a member of intelligent crowds.
