Bloglines Update
Great news, Bloglines addressed the "onfocus/nofocus" problem and the Greasemonkey script I wrote isn't needed anymore. I got an email from Paul at Bloglines letting me know that, "Our anti-XSS code was being too aggresive and attempting to filter attribute values, in addition to attribute keys." Thanks, Paul! I'm very happy they took time out to address the problem because I think it's a great service and I didn't want to move to another reader. If you installed the Greasemonkey script, you can get rid of it. I deleted it from my server.
