I'm riding the train back from Boston to New Jersey and thinking about the discussion on podcasting metrics at the Podcast Academy.
Lately, the discussion has turned toward what we know about the podcasting audience from surveys and other research. That's great - it helps us know the "who". But no one is addressing the methodologies for measuring "how many". I find that no one wants to engage in this very difficult discussion.
Perhaps these panel discussions aren't the right venue for this topic? If they aren't, then what is? When and where will we have it? This is where the real work will be done.
