Nathan Stuller's dashboard

I am trying to embed the Realtime Buzz Widget into my website and have simply taken the script and put it into my file. However, I am noticing that it does not always return the Buzz Widget. It always blocks out a chunk of white space in my page, but rarely will it return the widget to be rendered in my page.

Is there some sort of timeout that might be occurring? Or perhaps there is a usage limit? I am refreshing the page quite a bit while I am testing. I am namely testing on FireFox 3.5.2. I tend to have slightly better results when using IE 8.
