@cheeaun I love how this is shaping up, and group by author does feel more feed-reader-y. I like this idea of also tuning my Follows by who's noisiest, etc.

But! I have been yearning for a way to group posts that all reference the same link. As in "this link is getting a lot of traction among my Follows, and I just want to see what they're all saying about it at once". I don't know if that fits in with the Catch-up concept, or would be better as a thing all by itself.
