hacker news has probably been scraped too many times. that's why it's not working. it didn't work for me, but other sites worked easily. ...i will comment that the user experience for first adding elements is not what i expected. once u understand it's great overall, but i'd have some popup tooltip type guide thing going on for the first time a user uses it explaining that you should choose one element first, and then check a matching element. ...Then explain the number bubbles next to the property field. You don't get what those numbers are at first. ..Then for the property field, somehow make it more obvious that you should fill it out. Basically you have the interface setup so any action can be done at any time, but it should be presented as a forced sequential set of steps to the end user, at least at first.
