I'm curious as to the reasoning behind the podcast cut. If podcast content is so important to the site's fan base, doesn't it make just as much sense to leave the current bombcast as is and record a second one (presumably ~1 hour and more focused on a singular topic) later in the week. This creates a greater value in a category that the fanbase values, and in turn entices members to sign up for the premium membership to experience more of something that they enjoy. It also wouldn't incur any additional equipment/space costs as it's all there already for the original podcast - but would create value for the premium membership besides the token features (t-shirt, HD quick looks, etc.).
This just seems like the most obvious answer considering that they're leveraging a podcast to push memberships, though I think there's also additional opportunities for membership perks (forum/chat privileges, special events, etc.).
