I'm a great fan of Bloglines and have used it as my only RSS reader since Christmas. I just discovered another feature which makes me like it even more: Add the JavaScript on this page to your favorites and you can add instantly add blogs to Bloglines while browsing.
It works like a charm and even finds RSS link that are not visible and only referenced via <link> tags. They also improved the clippings/blog feature and added a full feature html editor.
Coolissimo!
