Online anonymity: Is there such a thing?
Our lives online have become a "sharefest" of Facebook status updates, Twitter messages and Flickr album uploads. Our memories, which long ago may have been captured in shoeboxes or as keepsakes, have been transformed into virtual scrapbooks. What may have once been shared with only our closest of friends is now shared with all sorts of acquaintances: some we know, some we think we should know and others we just pretend to know. And we do this without the realization that these seemingly inconspicuous bits and pieces of our lives in fact disclose personal, self-identifying information about exactly who we are.
Now you may be asking yourself, "What qualifies as bits and pieces of self-identifying information?" Well, the answer is information that is quite frankly meaningless to most. Details such as birthday wishes, school or work mentions, preferences for movies and restaurants, even a shout-out to your favorite home team can easily help paint a profile of who you are when pieced together.
Now imagine for a second that you are a passive social user like I am. You may say to yourself, "I never update my status, share pictures or tweet, and, therefore, the online world has nothing on me, right?" Actually, the answer is a resounding WRONG. Even if you are a passive social user like I am, be aware that YOU may not even be the culprit in painting your own profile online because, lucky for you, your friends are already equipped to handle this on your behalf. By commenting, tagging, even referring to any of your interests either mentioned or implied, your friends suddenly become the research behind the missing link of who you are.
The bottom line is that patterns of social communication are very telling and you can bet that those who want to find out who you are can easily piece together a relatively comprehensive view that, in the end, may or may not fully benefit you.
Who is looking out for No. 1?
It's no secret that our societal norms have shifted, resulting in the over-sharing of one's daily life. And like everything in life, there are defined pros and cons to this type of behavior. While the pros are completely subjective to the end user, the cons are definitely more substantiated and have been validated by experts who echo a resounding refrain of "proceed with caution" when sharing details of yourself online.
The underlying problem of sharing online to keep up with friends and family is that our information could be collected, mined and reassembled by unintended readers to create a profile of exactly who we are - even as granular as our personal Social Security number. Though that is an extreme example, it has been proven possible.
As the Federal Trade Commission and advocates work to make a case for protecting privacy for a technological landscape that has surpassed the current rules, please be advised that protecting yourself online is simple and best expressed by Jon Kleinberg, professor of computer science at Cornell University: "[W]hen you're doing stuff online, you should behave as if you're doing it in public - because increasingly, it is." Assess the risk before rather than after sharing.
The implications and personal ramifications of online privacy are abundant. What are best practices for consumers and ultimately advertisers who want to leverage this information to create a satisfying online experience, created through relevancy, for the end user?
For the consumer, the best safeguard is limiting vulnerability
Ultimately, limiting vulnerability begins and ends with self-regulation. You must regulate your online activity knowing that anyone - companies, governments and, yes, criminals - may exploit what you share without your direct consent.
Additionally, understand the stance that your favorite content site takes on your privacy. Is it your publishers' sharing policies that are exposing your interests and behaviors in ways that you may not have imagined? When in doubt, it's important to inform yourself and protect your own interest.
Seek out content sites that are explicit about what happens once you enter their site. Take, for instance, Dow Jones, AllThingsD.com. They are among a handful of properties that actually call attention to tracking that may be occurring on their site, greeting users with a message and instructions for privacy protection through the removal of tracking cookies.

There isn't one service, like the do-not-call list, that exists to protect your interest online. Therefore, it is up to you to read disclosure information, to read the terms and conditions legalese, and to safeguard yourself by putting your interest first.
For the advertiser, profile data reigns supreme
As those of us predominately within the media department know, a publisher's offerings are only as good as their ability to reach our identified audience. Trivial, commonplace impressions get a makeover: they are dressed up with data to make them more appealing, targetable and, well, more expensive. But the makeover doesn't stop with just one look - it requires refinement and reinvention. Thus, the cycle of data collection begins: models are developed, profiles are captured, tests are run, results are scrutinized, more data is collected, more profiles are added...you get the picture.
So what's so wrong with publishers refining their offerings to create a better experience for advertisers to align with and ultimately for consumers to experience? Well, the answer is not necessarily the behavioral modeling. It goes a step further into the tracking behind how the behavior modeling is derived.
Third-party tracking is out of control. Tracking that was once applied to a specific publisher's site is now exploited and shared with site after site, allowing providers to develop comprehensive consumer behavior profiles that are less than anonymous.
Consider the variables: we share more, the share is leveraged and online privacy concerns are fueled. But what is the real issue at hand? Is it really that our personal privacy has been compromised, even though we have been in the driver's seat the entire time? OR is it more likely that we want to benefit from the sharing of ourselves in bigger ways than we are currently experiencing.
And, thus, we arrive at the intersection of privacy and advertising, and at the start of a newly begun conversation. Be on the lookout for a unique, animated debate about online privacy in the coming days. Until then - stay safe and regulate.
