Here's a language consistency nitpick for you. :)
Some paywalled content is labeled as "Subscriber" (as in the videos pull-down, or the subscriber videos page), whereas in other places it's labeled as "Premium" (the tag on top of individual videos, or the upgrade page, or the premium podcasts page).
I would suggest that "subscriber" should always refer to the humans who give the site money, and "premium" should refer to the content they get, and you standardize on this. Content=premium, audience=subscribers.
