For a number of reasons, i’ve recently set up a new OpenPGP key, and will be transitioning away from my old one.
You can get the new key from: https://www.miceliux.com/~juan/pubkey.asc
And the transition document from the old key is here: https://www.miceliux.com/~juan/key-transition-2013-09-11.txt.asc
