I just use the name of the service. So for example it would be [email protected] for my Github Account.

Could just extend the logic and tie it all the way down to your house address. [email protected] and finally commit to a real-world identity to match the cyber one. Why not have a mail server in every house and then it's private and everybody can understand your email address. When you move house, the mail server spits out a thumb drive with your emails and deletes the local storage. You move email address to the new house. You could eventually replace the [email protected] format and just autofill the email for John at 124 Main St in St Louis.

For some reason (probably a good reason) the internet can never be grounded, we always are going to stick to obscure formats that don't necessarily line up with real life and then get surprised when gov agencies collect that data and corps make money selling that exact data, out from under us.

That gets unwieldy in a hurry for apartments and other multi-unit addresses. Not to mention 124 East Main St vs 124 West Main St.

Then what happens when John (who is actually John Jr., but never uses the Junior unless legally required) has a son John III? Then John Sr. moves in rather than to a nursing home.

Same as whatever people do with their physical mail. Someone goes by a middle initial or you add a title to one and not the other.

Your physical home address used to get printed under your photo in the 1940s newspapers. They stopped when people started to get murdered. I think there's good reasons we don't publicly ID off home addresses anymore. It sure would make life somewhat simpler if we could though.

Citation needed.

Were the murderers foiled by having to use the phone book instead of the newspaper? Was it the lack of pictures that stopped them?

Probably the photo and adress published together would make it much easier to trigger murdering psychopaths whereas phonebooks had no pictures. Just my assumption as I am not familiar with this practice, though I do believe it is quite a bad idea

For most services, the email address is also mandatory for verification, marketing materials and other stuff. So, from user experience point of view, it makes sense to use the email as the unique identifier for the account, as it avoids remembering another id for login.

Using 8 characters from a-z and 0-9 would be begging for trouble, starting with 0/O and 1/l confusion. Most humans are really bad with arbitrary alphanumeric strings.

How about [social_security_number].us

Its already unique and tied to each citizen.
