We already have identifiers on the Internet -
email addresses - so why
we would choose to carry over cryptic strings of digits from an
antiquated system and use those for one communication medium - while
continuing to use email addresses as the identifiers for others -
I'm still amazed at the number of (mostly small) businesses that I deal
with that have ISP domain names in their email addresses. Which seems
antiquated to me!
What geeks like us often fail to realise is that for many people -
especially small businesses - email is just a tool, it may not be central
to their business (ala they may not conduct a lot of business on it, but
need the means regardless) and resultantly, it's not their primary
Memorable phone numbers, on the other hand, make them readily available to
everyone within reach of a telephone, which is still more people than have
ready access to email. And by that I mean _right now_, not when they get
home to their computers.
Enum could be fairly useful as a bridging technology, if nothing else,
IMHO. And people who don't have the need for their own domain name, that
don't use an ISP based address (the future of which is determined by their
ISPs success or failure, and is non portable as previously observed) are
using a free email address (the future of which is determined by their
free mail providers success or failure, and whilst portable, is 'free' and
generally has service levels to match)... tying your long term
accessibility to an email address which isnt 'yours' may be as fraught
with difficulty as a phone number.
(And at least with number portability, you can move your number around;
much like you could a personal domain name.)
