Back in my (not so long ago) IE days, I was using Pluck as an RSS reader. I liked it, it was handy. Now that I switched to Firefox, I had to find something for RSS. Nice thing about Firefox, there are a lot of plugins available.
Sage seems to fit the bill. It has a sidebar for the feeds like Pluck did in IE. So far, so good. If you use Firefox (you do use Firefox, don’t you?), Sage would be a nice plugin to add. If you know of a better RSS reader for Firefox, let me know.
