I recently purchased a MacBook to compliment my Windows desktop machine. I am hunting around for a free RSS aggregator that I could use on both machines. Currently I am using Google reader, but I miss the ability to preview articles before I navigate to them. Additionally I do not want to manage two separate lists for each machine. It does not matter to me if I use two different products for each OS, or an online product between the two.
Can anyone recommend a feature rich, free RSS aggregator that supports article previews that I can use in a Windows or Mac environment?
