Do you see unread items in your rss reader as todo items?  Do you think you have to at least look at it if it is unread?  I would have to say I 'sort of' do see it as something I should at least look at ... and after reading through my subscriptions I prefer the unread items to be 0 ... but maybe I'm just weird like that ;)

For those of you interested in what I subscribe to, I just put the latest version of my opml at: http://jasonhaley.com/files/subscriptions.opml
