The Yahoo Search Blog announced that Yahoo has finally added support for the NOODP META tag. You can deploy this two ways;
META NAME="ROBOTS" CONTENT="NOODP" (stops MSN, Google and Yahoo from using ODP directory)
META NAME="Slurp" CONTENT="NOODP (stops just Yahoo from using ODP directory)
I reported back on October 11th that this was coming and Danny explains why NOODP tag support is not enough, we need it to support a method to tell Yahoo not to use the Yahoo Directory title and description as well.
