This is odd. A colleague sent me a link to this article, about the fact that big name advertisers and their media buyers are avoiding social networking sites, due to the risk of being associated with objectionable content.
But speaking of bad associations, check out the first hyperlink in the article: murdered. It currently links to an article about a Playboy spread on MySpace. (image at right shows link on mouseover) A veiled social commentary, perhaps?
Interesting article, though.
