Monday poll: Should PR firms ghost-write client blog posts?

I asked this question in May last year. At that time the consensus was 'only if you state clearly that it's bylined.' Well, here we are a year later and there are millions more blogs, and innumerable corporate blogs. How do we feel now? Have corporate blogs been taken over by the marketing department? Do we believe the posts are written by the author themselves? Are agencies madly penning posts on behalf of clients? Or are the authors still authentic? Is transparency still part of the blogging vernacular?

Have things changed? Should PR firms ghost-write client blog posts?
