Fandoms are easy in the sense that the material of the board comes at its core from a world already developed - Sure there's still the question of plot or theme, but the background is already set up. Some historical periods probably fall under this too. So my question focuses specifically for boards that are promoting "all original content" in their genres. As a member, what's the middle sweet spot between no detailed lore and a world "too" fleshed out (possibly making it intimidating to join under a feeling of stuffiness)?
I personally like the "skeletal" setup where the boundaries are there, with detail, but open to interpretation. When I see like 20 pages of various nuances I start to feel a little overwhelmed and afraid of being "that Newbie" that steps on everyone's toes and assumed not to have read anything. On the flip side, a well-detailed world is more fascinating then just another "xyz genre rp".
