I've just started House of Chains, and after reading 40 pages or so, I've flicked ahead to find that the first 150 pages are all about this fairly one-note Karsa Olong chap. I've also found out who he becomes, a character from Deadhouse Gates I didn't find at all interesting then either. So my motivation for skipping this section is pretty high. Will I miss much, either in terms of this part of the story, or info that will be crucial to deciphering the rest?
