Ever since Google decided to shutter Reader (which upset me greatly), I have been looking for a good RSS reader. I've used Bloglines in the past, and really loved them, but they are not the same as before they were bought out. That's when I switched to Reader, and when they decided to shutter, I switched to The Old Reader, which very reminds me of an older version of Google Reader (hence the name). But I've never been quite happy with it, and then I discovered Feedly. It took a little getting used to, but I absolutely love it. It's cross-platform, and includes a web interface as well, so even if you use multiple devices, you can keep your feeds synced up. That is probably my favorite feature.
So, what's your favorite RSS reader?
