An initial version of the 'feed updates' page is live. (See this post for the background.)
It's nice and simple, just listing those sites with unread updates, how many and since when. A 'mark as read' check mark is shown next to each when logged in.
This is, obviously, only intended for me as it reflects my unread status in /reader. It's an experiment to see how if affects my reading behaviour.
An extra option has been added to /admin to choose the default view of /reader so that I can switch between this and the standard 'items' view. This doesn't affect the view when not logged in.
