An interesting start
I like the idea of it. Sort of like "Fever" without having to run your own server.
The problem is, I currently use Reeder on the desktop and on my iOS devices; often starring things on iOS that I want to read on the desktop when I get back to a computer. Cream doesnt really work with this workflow at all because it doesnt support favorites/stars. So really how I currently organize things doesnt work here at all. So its mostly an issue with how I currently do RSS; this may be good for someone who doesnt have such an established workflow.
