Phil Wolff interviews Steve Rose, creator of RSSJobs. One part I took note of:

Q: What’s on your wishlist for news reader features?

A: I would like to see an RSS Reader that could manage the items from an RSS feed as individual items. A user could archive specific items for viewing later after it is no longer included in the feed.

NewsGator works this way today. Very important, as we’re often reminded from some of our business customers.
