com.example@abc
Although I think that would just confuse most of the world.We could go oldschool with a newline:
abc
example
com
;-)More seriously, I wish there was an easy way to divorce the username from the server similar to how DNS works so I could move my provider without losing my identity. A separation of name providers and service deliverers would do this.
Also, do we need names to match domain names? Couldn't we start from scratch?
It would be interesting to see what we could come up with if we dropped .com, .net, .org, .name etc and went for something more abstract.
.blue .horse .cheese .bang
While we may end up with just the same as now (but without the .com) it might be interesting.
