Our Ideas and Additional Information:
The obvious would be a play on a "Keg of knowledge" being tapped somehow. Or a mockup of a brain being tapped for ideas and knowledge. But, I don't want to restrict it to only that, it could be largely texted based too or a creative use of text and imagery. Looking for something to really stand out. Also need a version of logo that will be the right look and dimension for an iTunes Podcast logo (square).
