I agree with the previous commenter that, perhaps, you could separate out "like" (to get recommendations) and "follow" (to get future updates) actions.
When I first signed up, I followed only shows that will have future episodes, but I'd love my past favourite shows to impact recommendations.
I love how the action unfolds at the end, each show competing for most buzz across Twitter while the tweets are streaming by! Nice work on lining up the commentary with events from the Emmys!
