This is a cultural thing. By selecting a personally-meaningful name (unique or not) you give a person some form of self-expression. This self-expression can be related to online presences. It could become culturally common to do so. But it loses the connection to ancestors that our current naming culture has. My name (first, middle, last) refers to some of my ancestors. I would not change that name. I have a few screen names that I highly favor and use in emails, forums, and gaming high scores, but I still also like my given birth name for it's genealogical associations that link me to my identity across generations. Similarly some people's names are chosen for religious associations. In any case, will we abandon our current naming culture in favor of personally chosen names in the style of online identities?
