This makes me very happy

From the Google Reader Blog:

Hide unread counts

We've heard you loud and clear. For some of you (and some of us on the Reader team), unread counts are a source of anxiety and can feel more like a to-do list than the random awesomeness of the Internet. So to help you sleep better at night, we've added the ability to turn off unread counts for each section of navigation independently. Subscriptions with unread items will still appear as bold, and you can see the number of unread items if you hold your mouse over the subscription name. To really set yourself free, try turning them off for all sections. (Ahhhhhh, now doesn't that feel better?)
