Who's behind the blogging.

I found this a bit amazing. Evidently Wal-Mart has been sending talking points to various bloggers.

But the strategy raises questions about what bloggers, who pride themselves on independence, should disclose to readers. Wal-Mart, the nation's largest private employer, has been forthright with bloggers about the origins of its communications, and the company and its public relations firm, Edelman, say they do not compensate the bloggers.

But some bloggers have posted information from Wal-Mart, at times word for word, without revealing where it came from.

Glenn Reynolds, the founder of Instapundit.com, one of the oldest blogs on the Web, said that even in the blogosphere, which is renowned for its lack of rules, a basic tenet applies: "If I reprint something, I say where it came from. A blog is about your voice, it seems to me, not somebody else's."

Companies of all stripes are using blogs to help shape public opinion.

I'm curious about other's opinions on this practice. After all I'm sure many organizations sends out emails that get used in blogs. It may be that not informing readers is the real issue here.
