Give that the Daily Mail and Mumsnet are targeted at the same demographic (middle class women age 25-54), would it be cynical to say that this hacked out "Why-oh-why" article was a planned piece of cross-promotion for the two?
Has the customary gushing article "Why I love X" (where X is the product/service/programme/whatever slated a couple of days earlier) article appeared in the DM, where X in this case is Mumsnet?
