Do you not see the problem with sponsored content or (I assume) paid for case studies? We do not want our writers to be aware of ad campaigns when they're writing something. We've run relatively negative content for almost every single advertiser that's ever bought spots on Ars. Do you really want them having any level of influence over what people write?

We run buying guides quite somewhat regularly. Our audience doesn't want more buying guides, though. They basically want what we already write.
