First off, I like the recommendations, and the learning algorithm seems decent. However the UI continues to give me nightmares. I setup a list similar to what I have in Zite or Flipboard. For some reason only Chrome will let me actually go to the list and scroll it. For everything else (IE, Firefox, Opera) I can see the list, I can click on the list, but I can't scroll the list.
While I like the recommendations, I would also like the ability to have more control over sources, and to control the refresh rate. Yes I "get" they think that isn't needed if they are doing this right. I just respectfully disagree.
Just my .02 worth. I wish the team well, and hope they have an Android App version of this eventually as I would love to have the pretty on my Sony Tablet S...
