I have to admit I didn’t do any research and assumed that .me was available to anyone because I noticed it around the same time domains such as .app, .blog, etc. came out. Honestly thought it was supposed to mean something like ‘Hey it’s me’.
So I registered <surname>.me for me to use <name>@<surname>.me as email address.
My surname with generic domains such as .com, .net, etc was already registered and didn’t feel like registering my full name. This is pure laziness, didn’t want to use something like hello or contact @<fullname>.com as email.
