Unfortunately, personality clashes have taken over the search for Sharon's identity. Matt and a former poster here are in a battle (who "started" it and who is to blame are irrelevant). Both have contributed greatly to advancing the search, but are at odds with each other.
The sad part of this is that the answer is at hand. If the rumors that have heard are correct, we will have an identity for Sharon in the next couple of months. Both people will have played a part in the solution, but neither will likely acknowledge the other's contribution. It is unfortunate, because both researchers deserve our admiration for what they have accomplished.
