I’ve used first@last.name for the last 10 years or so. There have been probably a half dozen web forms where a regex expected 2-3 characters and I input an old gmail account that forwards to this address. Over the phone, the first@last part is easier to communicate since customer rep generally has the name info already. The .name throws them for a moment, but I’ve had one or two even tell me “oh, that’s cool, how did you do that?” which feels nice. It wasn’t my first choice, lastname.com was taken, but I like the precision of .name, arguably the most accurate TLD for a personal email address.
