Finding people on Facebook relies largely on knowing their name, or recognising it in someone else's friend list. And usernames for Twitter are often based on a person's name. In some social media cases you can't even change the username at all after you've set up your account. Your username, and thus your real life name if they're related, becomes a marker of your presence and a trace of your wise (or not) thoughts.
Not changing your name when you marry* has been stereotyped as the preserve of the professional middle class woman, who is possibly motivated by feminism, but more likely seeking to continue her "brand" in her chosen career. I suspect there are in fact quite a few cultures where keeping your name is more common than changing it, but in Aotearoa New Zealand I still get called Mrs more often than Ms.
Your thoughts, dear readers?
* Does anyone know if there's any data yet on name changes with civil unions?
