In addition to Phil Taylor, the Bay Area site's first two hires were Japanese-American and African-American columnists. And I saw Chantel Jennings (formerly of ESPN) wrote an entertaining oral history of Harbaugh's Saved By The Bell appearance for the national CFB site.
I haven't looked at the roster across the nation, but I don't think the diversity criticism holds up. However, if what you're after is for a new site to assume that unknown and unproven writers are the way to attract readership, you're probably not going to be fulfilled there.
