Partially, yes. However, it all boils down to how you use it.

I don't download keys immediately, I much rather have a fingerprint
exchange after seeing some off-band id. Of course, many countries don't
have any kind of id, which makes it harder.

However, unless you have signed the key, you get a message like:

[rms@roque apache]$ gpg --verify mod_ssl-2.8.12-1.3.27.tar.gz.asc
mod_ssl-2.8.12-1.3.27.tar.gz
gpg: Signature made Wed 23 Oct 2002 09:48:27 AM WEST using RSA key ID
26BB437D
gpg: Good signature from "Ralf S. Engelschall <rse@xxxxxxxxxxxxxxx>"
gpg: WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the
owner.
Primary key fingerprint: 00 C9 21 8E D1 AB 70 37  DD 67 A2 3A 0A 6F 8D
A5


You see, that WARNING: is not there for nothing... it's there to WARN
you that you don't know if that's really Ralf's key or not. I'm still
waiting to meet him in person :)
