Amphetadesk (http://www.disobey.com/amphetadesk/) is a great RSS feed reader. I use it to track 20 or so different news sources a day. However, I mostly subscribe to feeds that include copious content, and once I determine there are no new entries on a feed I still have to scroll down fifteen screens worth of old content to see the top of the next feed.
To speed the process I make a quick 5 minute template hack that provides a "jump to next" link in the title banner of each entry and a corresponding anchor in each title. Since the jump link is always in the same place relative to the start of each new feed listing, I'm able leave the mouse in one place and check the top of each feed w/ just a series of clicks. Like I said handy, but trivial.
