If you've shared your library with more than a couple people, than you know what comes next - people asking you to add shows. You could do it, but it very quickly becomes an unmanageably large tv show collection.
A better way is to mimic the Android experience of a drawer with the full list of all shows that you pick and choose from to curate what you see in your library. This would empower users to share their libraries more, and maybe even sell access to it? Not sure on that one, but anyways, I'd really like the ability for people I've shared with to curate their own library out of what I shared with them.
