[$] A schism in the OpenPGP world

The OpenPGP standard for email
encryption has been around since 1997, when it was derived from the
venerable Pretty Good
Privacy (PGP) program that was released in 1991. Since it came about,
OpenPGP has been the decentralized, interoperable way to exchange encrypted
email, though
its use never really took off as advocates hoped. Now, though, it
would seem that a split in the OpenPGP community threatens to
fragment the OpenPGP-encrypted-email landscape, potentially leading to
interoperability woes.
