Just a curiosity question really, how are the featured sites to the right determined? I only ask because it seems it is almost always the same 10 or so sites rotated in and out. I was bored one day and refreshed the page about 50 times and one of two of the following:

Penumbra, Horizon and the Scarlet Hand

showed up every time. Now, this isn't a problem or anything, like I said, just curiosity

There are currently 12 featured sites in the rotation, and they are randomly selected to be displayed in javascript (so it's different from each page-view). It's just completely random.
