Personally, I'm watching this community because I want to start diversifying my book spend and book time. I don't have the same level of interest in fanfic these days, and I wouldn't get as much from the community if a high percentage of the posts were focused on fanfic recommendations.

Whatever the majority wants is of course whatever the majority wants. But if we start including fanfic recs, I suggest we adopt some conventions for labeling posts clearly as either BOOK or FANFIC so people like me can skip or tune in as applicable.
