Memory leak

I’ve been having some problems with the site recently and have concluded there’s a memory leak related to the intelligence filter. If I open Newsblur, it works ok, but as I click around to different feeds the memory usage starts to ramp up. If I load the site and immediately slide the intelligence sorter from red to green, the memory leak begins and locks the system up. I replicated this in Chrome, Firefox, and IE (all on Windows 7).
