Peter A Mayer, a New Orleans advertising agency, has put together LivesConnected, a flash-based oral history of the experiences of those (staff members*) who survived hurricane Katrina and its aftermath.
Organized by respondent and key issues in their narratives, the quasi-network layout appears to be pure design (i.e., not theoretically driven). But it's easy to see how social scientists might use similar techniques to publish fieldwork interviews.
* The site is vague on this point, but I've looked at roughly a quarter of the interviews, and so far all appear to be caucasian (NOLA was 67% African-American in 2000). Thus, it doesn't seem to be based on a random sample of (former) NOLA residents.
