I'm an avid RSS enthusiast, so I have tried out several services since my beloved Google Reader was retired back in July.
Currently, my chosen service of choice is Feedly, which I use on both mobile devices and computers at work and home. I also tried out the Old Reader and Newsblur.
I looked at both Flipboard and Zite and they're not for me. I actually don't prefer the magazine style, and since I already have nearly 300 RSS feeds, I don't feel like I need completely new sets of content.
If my goals with RSS were more social-- sharing content with friends, reading linked content, etc. Flipboard would be my choice over Zite. Since I just want to read the content I've cultivated and collected over the last 9ish years... I'm sticking with Feedly.
