and I frequent both. SPS is a pretty top-notch place to find out about all things MSU as well as various overall sports. SPS seems to have moderators that are much more interested in keeping this place strictly a sports message board.
Nafoom, on the other hand, is a good place to go to find out what other ppl think about certain TV shows, how much itunes sucks, where and why you left for you summer vacation, and, ofcourse, other ppl's taste in music.
