So, the Miley Cyrus v Sinead O'Connor ding-dong thus far:
O'Connor writes an open letter to Cyrus in the wake of the 'Wrecking Ball' video and her appearance at the MTV VMAs, warning her of the dangers thinking "it's somehow cool to be prostituted".
Cyrus responds with tweets mocking O'Connor and her past mental health problems.
An obviously nettled O'Connor demands that the tweets are taken down, saying in a tone as well as "a spirit of motherliness" that "It is most unbecoming of you to respond in such a fashion to someone who expressed care for you".
Amanda Palmer butts in with an open letter of her own, remaining ever respectful to O'Connor but arguing (essentially) that women in music should feel the freedom to dress and behave in any way they want. (This, for me, hits the nail squarer on the head than either O'Connor or Cyrus.)
The Guardian's Stuart Heritage reacts to the developments with an open letter to open letters, when it might have been more interesting to hear from Peter Robinson, given his recent article exploring whether nudity in music videos is exploitative and cynical or artistically justifiable.
