I'm currently querying agents for a novel, the first in a series of (I think) three to four. I have ideas for short stories (one ready to pop out) and vignettes related to the cycle. I want to put them out there for free both to get them out there and to hopefully build momentum. (Eventually more related material would go here, including some short stories after publication.)
What would you do? Start a new blog for the world of the stories? Is there a better venue for this sort of thing than a blog?
 Of course I'm assuming publication for the novels and shorts. No point in aiming low. 8^)
