I think online RSS readers like Google Reader suck - I vastly prefer desktop ones. For many years, I used SharpReader. I liked it and it's free - what's to complain about?
But it's no longer maintained. The last update was "Changes in 0.9.7.0 - released August 2 2006" and there were more and more of my blogs that were just throwing feed errors that weren't actually errors.
So reluctantly, I look around for a new one. After a bit of research, I settled on FeedDemon. Took me a while to get used to its quirks but once I got over the initial learning curve, I'm quite happy with it.
And since I could export my subscriptions in opml and import them into FeedDemon, I didn't lose a single one.
