JKR and The Death of A Theory.

Recently, we have been debating whether JKR's statement that the Half
Blood Prince is NOT Harry or Voldemort was a devious way of planting
the clue that it was indeed Tom Riddle. There are hints in the book,
that we could treat Tom and Voldy as separate entities.

However -

JKR flat out said, that it is NOT Tom Riddle. If it's not Voldy then
it's not Tom either.

Darn, I sort of liked that theory.
