That's true. But "Dan", "Dan Brickley", @danbri etc.. are literal 
identifiers that all have a common referent, in our so-called "real 
world" medium. Thus, I would encourage anyone publishing a document 
about you to use the most unambiguous identifier, in relation to the 
medium of communication.

Remember, there was once a time when middle names (or at least middle 
initials) were really important when referring to People, in our 
so-called "real world" :)

I struggle with your "nitpicking" characterization. This isn't about 
nitpicking, it is all about giving folks appropriate guidance so that 
they can operate in this Web medium effectively.

None of us where taught at school to refer to things unambiguously. Why 
take that approach on the Web? Just because the medium is digital i.e., 
different from our so-called "real world" ?
