I am a little late to the discussion.
Personally, I do not read the AP Fiction and would rather see the space used for something else {Support Articles, Map Support, Etc..}.
When I want to read fiction, I resort to the pathfinder Fiction line.
The reason I buy the Adventure paths is for two reasons:
1) Quality of the Adventure Path writing
2) Support Articles {usually they interest me}
Cheers!
