Some constructive criticism:

1. Making the blue background lighter or changing to a different scheme may be easier on the eyes and less agressive

2. Please use a custom theme for the jquery-ui widgets (like the autocomplete). It's like default and it doesn't match the page

3. I don't think blocking the search button is a good idea, if the autocomplete goes slow or the user is fast it will create the illusion of a broken button.

4. Give the search button a little bit of button style

5. I don't like the sign on facebook popup that gets on the way of the search, maybe putting it on the results page would be less anoying making users click on sign in only when they have tried and liked the application.

6. If you don't like 5), at least put the 'No thanks, show me generic results' on a button, something green or so, like the search button

7. Fix the 'Sorry! No items match this filter.' message, it's only text, you can do better using some cute images and inviting the user to re-search or change tabs.

That is about it, looks nice.

Thanks for all of the tangible feedback - really helpful. Especially love the cute image instead of text. Thanks!
