Travis here, I'm the OP and also a co-founder of Fireplug, the service offering retroactive "credit" for your article history on Google Reader.<p>Our service isn't necessarily a replacement for Google Reader but a way to track what you read and more importantly what you learn online. It's kind of like last.fm's scrobbler except we can go a little more in-depth because it's relatively easier to analyze text over music. Our goal is to help users establish and build their online reputation and what better way to do that then leverage the dozens if not hundreds of articles they read every day.<p>Love to hear any comments/concerns/feedback you might have, feel free to comment here or email me directly at travis [at] getfireplug [dot] com and I'll be happy to help.
