I've been a user of OpenPGP for some time, but I've been using an old 1024 bit long DSA key, which I've now revoked. Instead, I'm moving to a more complex key setup, based around a master key (which is the one I will get people to sign in future), and regularly expiring subkeys.
This enables me to use the same keys at home and at work (tying the two identities together), although it will lead to a transition where my key is untrusted. I hope to deal with enough geeks over time to rectify this. For now, though, if you see stuff from me signed with key ID F2E084D6 or one of its subkeys, don't panic - it's my new key.
