So, I've recently come across individuals and even groups of writer friends (and seen people on the forums) who are extraordinarily creative but don't have any plans to say, write a novel themselves.
Some build worlds.
Some develop characters.
Some outline plots.
We have threads and posts in here like "here's this character, if you want him" or "I've got a world with no plot" or "I've a plot and no characters" and any combination in-between.
First off, I love this aspect of HW. That we can all sit and go, "Look, I have this character that I love and appreciate but doubt I'll ever write his story, would you care to do it for me?" It's an interesting concept and unique among a lot of people who don't want to share anything for fear of plagiarism.
So I'm curious:
What do you as individuals, as HWers, see as your strong point in writing?
Does world-building terrify you?
Are plots thick or elusive?
Do you have wonderful starting ideas but hate trying to figure them out in a novel?
And, have you ever considered of going into the business of, say, world-building and selling your worlds to other authors? Or character-development and selling (or fixing an adoption fee) for your characters? I've often thought that it's a shame the writer's market doesn't actually have this all thought out. That there's no market for creative people who are much better at one aspect than the other (Because, honestly, haven't we all read books that had wonderful ideas and we wished somebody else had actually written the story?
)Me myself, I would happily write strings of dialogue and sell it to people.
But I also enjoy most aspects of writing--plots not being my strong point, I'd buy those if the market existed! 
Anyway, I'm just curious to know more about you, my fellow writers and what ya'll think of this.
I remember hearing that about The Three Musketeers, and also Count of Monte Cristo, which Dumas co-wrote with Auguste Maquet, "with Maquet outlining the plot and characters in draft form and Dumas adding colorful dialogue and details. At the insistence of the publisher, Maquet's name was left off the title page, and in return he received generous fees"~Wiki article. 
(Similarly, in the free/open-source software world, unsolicited ideas are often ignored, but contributions of code are not.) Further, HW is hardly the only site where ideas are bounced around with money never being mentioned, so why would someone pay for them?
The more I read about publishers the more I realize they really haven't changed as much as I thought they had....
