there is an algorithmic feed, several of them! I follow one called Whats Hot Classic, and another one for just star trek related posts called The Promenade. But you can CONTROL the feeds and make your own if you want.

Oh yeah....I kinda forgot about what's hot. I guess I meant more like, you know. There's no mysterious one that decides who does and doesn't pop into your feed based on unclear sets of factors. I need to subscribe to more feeds...
