Let me know if you are particular features that you would like to see in the API. Also, if you plan on using the API please contact me, so that I know you are using it :-) I can provide example JavaScript files for accessing the API.
A request .. not for the API but for the site itself. When I click on an item in the left pane (the "Live Feed"), what happens is the content in the right pane (the "Review Store") is updated with the item I clicked on. However, that isn't intuitive and only realized that is what is happening after coming back to the site a few times. Can there be some UX improvement on that? If needed, maybe some animation or something to show how the click on the left results in a content update on the right?
Additionally, what would be a useful would be a "latest additions" view, so that I can see just what is new.
And lastly, ... a contact / feedback mechanism for requests like this perhaps?
