Do you use GPG to encrypt or sign your stuff? E-mail, documents, or your entire hard drive (with TrueCrypt)?
I use 1Password and an encrypted disk image now and then, but haven't yet found a need to use GPG. Security precautions for me have revolved around making sure data is safe if my laptop gets stolen; I don't sign my e-mail or anything like that yet. These days we have things like FileVault and BitLocker for encryption... have you found a need to use GPG either in addition to or as a replacement for other security programs?
I also sign security advisories and patches while wearing my FreeBSD Security Officer hat.
