A corrollary community of writers would be wonderful, though I do think it would likely require the backing of an institution parallel to Ycombinator.
Fortunately, there are many organizations that offer community for writers; most major cities have writing centers such as Richard Hugo House in Seattle, or The Loft Literary Center in Minneapolis. If you're looking to connect with such a community, these types of places are wonderful resources, though they tend to be offline focused.
