> So, how does your email address compare with these criteria?

Your description of criteria perfectly matches my own take on the matter. Unfortunately, the .com for my domain is already taken (but not actually used, evidently), so I went with singularit.us for Singular IT, LLC. I got as close to the ideal as I reasonably could. Maybe the .com domain name will open up in the nearish future.

edit: By the way, Andr??a Coutu (who wrote 7 terrible secrets revealed by your email address ) evidently doesn't know that one should Use RFC 2606 Example Domains For Example Emails.
