Unshared is pretty cool.
However, I mostly follow the most active users (and people I know personally), so my hub is basically identical to "Popular" most days. >50% cross-population of stories. I want a place where I can discover popular posts by people I'm NOT following.
Why can't "Discover" be a link in addition to a menu header? It could go to the most-shared posts that AREN'T in my hub. With the subtraction of followed tags, I feel bereft of content that's not just from the same four people.
