I'm going to speak frankly for myself. If there's general disagreement with me, then I will accept that, but this has been bothering me.
The reason people ignore your story is twofold:
1. The conventional way community forts run is that non-players writing fluff work around what the player posts. This is because a big part of the fun of DF is that the player doesn't have absolute control. If you desperately want to see a particular story thing happen, ask politely, bearing in mind that what happens on their turn is their prerogative, or you take a turn yourself.
Demanding that the player write your fluff into their turn, even if it inconveniences them, is just straight up rude. They're finding time to do something they enjoy, and you're telling them you want them to do something you enjoy instead. Be considerate, please.
2. 99% of the stuff you guys have written makes little sense in-game or is entirely divorced from what's actually happening/present in-fort. This apparently doesn't bother you. I intentionally wrote hooks for you guys into my story posts (the perpetual motion machine? Quill's journal?) that made sense in-game, and you either didn't read the post or ignored them.
At least offer others the things you demand of them. If you want them to respect your fluff, you'd better respect their fluff. That's more-or-less the foundation story heavy succession games are built on.
Rant off. Like I said, if I'm the only one that feels this way I shall suck it up and just enjoy the fort, but I felt it needed to be said.
