Anonymity is valuable to the structure of the Internet, but as the identity of a person becomes fluid, the reputations and identifiability of someone’s online presence becomes increasingly valuable. While jobs rely on user-submitted references, as do academic applications, many also turn to your social media presence or to your search results to gauge reputation. Privacy by obscurity, as records are digitized and indexed, is no longer as viable. But, there is no consistent form of identification across the web. Each service relies on its own username as identifier, with character limits abound, and your ability to hold the same username across services relies on both the uniqueness of your username as well as the date you joined the online service. But are usernames outdated? A self-selected identifier, varying from service to service and format to format? As Mat Honan puts it, ““One of the best things about the online world is how it lets us be whoever we want to be. We shouldn’t have to sacrifice that just because someone else got there first.”
The advantage of a username is that, at least within a service, it “refers unambiguously to a particular person”. That works fine if you know the username of the person, but often you may only know their name. Luckily, with services like Facebook, a person’s unique identifier is their name, provided they haven’t pseudonymized it. Once you have connected with that person, you expect (within the relevant online service) when you type in their name, you will be returned with precisely the person you were expecting to find. The difficulty with this system is finding out the username of another person, and confirming that the person with their name online is really the person you’re looking for.
