The problem is that you probably aren't seeing all the posts. If you are just viewing [s4s] through the /s4s/ board, you don't see the green posts, the posts with letters in their ids, or anything numberless. Together, those make up about 40-70 percent of [s4s], depending on the day. So conversation will appear disjointed and spastic, because you won't be getting the full picture.
I actually just flipped over to the /s4s/ interface to make this post, and it's pretty funny how unintelligible [s4s] is like this.
