It's a valid concern. I'd be willing to bet there are even quite a few WoW.com staff writers who don't particularly like the fact that when someone runs a Google search for their name, many of their WoW.com blog entries appear at the top of the search results. It really just depends on what industry the person works in, among other things...Many journalists and copy writers take on freelance/independent contract gigs like WoW.com, but Warcraft and/or video games isn't that person's "dedicated" industry.

A news writer, for example, usually wouldn't want his freelance work from WoW.com to flood the top results when someone Googles his name. The same is true for technical writers (like the original poster) who work in science or medicine; from their standpoint, it just isn't professional when most of their published work (industry journals, essays, etc.) is buried beneath "fantasy stuff with dragons and elves," which is what non-gamers would see it as. Generally, this kind of thing wouldn't be a huge obstacle to professional writers...but because of Warcraft's popularity, WoW.com's Web traffic and its SEO prominence, most of WoW.com's blog posts will always register higher up in Google's rank than a writer's dedicated industry work. But hey, at least there's a compliment in this; it's a testament to WoW.com's success.
