If you've sent me email in the last 18 hours, I haven't been able to read it and may not be able to do so for some time. My mail provider has had an outage (8+ hours so far) and is claiming that it will still be hours before service is returned.
UPDATE (2005-11-12): Email is still down. Could turn out to be days. Looks like Merlin Mann uses the same mail host.
UPDATE (2005-11-13): I woke up this morning and mail was working. Unfortunately iMac isn't.
