Bloglines rocks. Since I started collapsing more feeds and using the Hotkeys I can plow right though my whole feed (clipping on the way). Firefox 1.5 seems to has hosed clipping and I did loose some related extensions, until I downgraded, upgraded, and didn't check for updates to extensions.
And I'm awaiting Bloglines 3.0 "Bloglines switched it's user-agent from 'Bloglines 2.1' to 'Bloglines 3.0-rho' on Tuesday afternoon. ... there could be some big changes coming in near future."
