I get 2-3 emails a day updating me on the most recent news from AdAge.com. Do I really need a podcast from them too?

YES.

Why? Because it's one more way for me to get my advertising news. It's great to see the headlines for the day, and on average I read 1-3 articles a day from AdAge. It's also great to watch content on their website (minus the fact they insist on using Window's Media Player---ICK!) But for me, and other consumers out there, having audio content that I can listen to on my way to a meeting, or struck in a traffic is a great way for me to continue my advertising news for the day/week.
