Well, it looks like I was wrong about the Bloglines Continuous Update script being outmoded. Though Bloglines does display a running tally of unread items in the page title now, they don’t take the obvious next step of using their own API to see if that number is up to date. So I took out all of the code that counted unread items and displayed the total (which was a lot of code), and now all the script does is check the API for updates and reload the subscription panel if it finds them. Get it here.
