What are you using as an RSS reader? What do you like about it? Dislike? Any features that you just can’t seem to get?
Me, I use a couple of different ones
Livejournal shows the whole story (for most feeds), which I read as part of my friends list. Good for feeds that update sporadically, and conversely for those that tend to update many times in a day. However url changes to a feed are hard to fix and easy to miss.
Yahoo home pages lets you do headlines or summaries. It has one box per feed and you get your x number of stories whether that covers two hours or two months.
Neither of these allow me to say “I’ve read this story already”
