I love the concept of PGP and how well it seems to be integrated. I also don't know a single person who uses it or a provider/software capable of decrypting it. I think that's the biggest issue with PGP. Short of asking someone directly, you don't know if they'd be able to receive a PGP encrypted email, so you wont send one.
