Fluid SSB not auto-refreshing

I am using socialthing! in Fluid as an SSB (Site Specific Browser). I wanted to use it to replace Twitteriffic, but it seems as if it is never refreshing with new items, or doing any of the other stuff outlined in the blog post about fluid integration. I was wondering if this is a bug, or if I am doing something wrong. I have it set in fluid so when I quit the last browser window it only hides the window, so any fluid API calls and/or ajaxy stuff should be coming through.
