Hi,
I am a new member. While registering my gpg key to pgp.mit.edu, it would not accept my key!! The problem turns out that it doesn't understand GPG keys with a photo-ID. After some googling, it turns out:
1- pgp.mit.edu doesnot accept some key formats
2- pgp.mit.edu mangles other keys
3- hkp://subkeys.pgp.net is a much better alternative, as it load balances over many physical servers
4- hkp://subkeys.pgp.net is the chosen default server now in GnuPG configuration.
I am suggesting recommending that server on the web pages
