More ideas occur as I am reading the comments:

1. Please make the default home page people we are Following. We're following them for a reason.

2. Add a bulk-editing feature so I can select many responses I'd like to delete.

3. Don't lump together responses with actual stories. It's annoying, to me anyway. Who wants to see a bunch of "Great writing", "Enjoyed this piece" (I mostly add additional comments, but that's how many of mine start).

Improve Lists functionality: again some kind of bulk selection, and let us add a story to a list from our Draft, instead of having to remember to go back to the published piece to do so.
