I don't know if this topic's been talked about before, but here goes: This isn't exactly a suggestion for a new in-game feature, but more of a suggestion for Dwarf Fortress in general.
DF is an amazing game, everybody knows that. The fact that everything's done by just Toady and his brother makes it even more amazing. But wouldn't DF, and everybody else in general, benefit if more people are helping? Crowdsourcing. Right now, this is what the suggestion forum is all about, yes, but I mean more than that. I'm talking about having more hands actually helping out with the coding, the balancing, the information, and all that. I know that if given the chance to help out and effect change in DF, I'd do it in a heartbeat. I'm sure a lot of you would too. And, I'm sure a lot of us have something to bring to the table. I'm shit at coding, and my (soon) EE degree doesn't really matter much in the world of Dorf Fort, but a lot of people here can code, or do know a lot of things that are relevant to Dwarf Fortress. (The guys who made DFHack and Dwarf Therapist come to mind, for example)
What I'm saying is this: What if instead of just the two of them doing all this on their own, we actually help out? I'm not saying I don't appreciate the work that's been done already, or anything. Frankly, I am amazed at the sheer volume of work that's been put into this game, and I really just want to help out, and add something tangible. Don't you guys want to help too?
