1) Love the domain, love the name. Simple. To the point.
2) Looks like a bad clone of the Medium homepage. Not that big of a deal, just what I noticed.
3) Needs a lot of UI work. A lot. Images don't look good on the retina macbook. Icons are all different sizes. The main blue for everything is too dark.
4) When I signed up... You sent me my password via email. NO! Stop that right now! In fact, if I could delete my account after that... I would.
5) When you add a feed, why is it an option to tell you how often to update it? Should just be automatic. Don't make me think about it. 5-15 min should be fine. 1 hr or more seems too slow. There are lots of API's like http://superfeedr.com/ out there.
6) Why is there an add funds button? What does that do, and why should I add "credits"?
7) Your doc page needs to be much more user friendly. Again, don't make me think.
Overall, I wasn't trying to be harsh. I like the idea, and you could have something in the future. The implementation as is needs some work though.
