The idea is that you have a key that you keep *extremely* secure. When
you go to key signing parties you only bring the public key (for
verifying the fingerprint) but you don't sign keys until you're at your
secure host, for example.
That is the key you will use to establish yourself in the web of trust.
The key you will actually *use* is a child key signed with that key,
and perhaps a handful of others.
That way, if your everyday key is compromised, you can still use your
secure key to sign the everyday key. This alone will get you "marginal"
trust in the PGP web, which is good enough to get you new credentials.
