Word to the wise: mind your p’s and q’s and remember that your electronic footprint looms large. I do not allude to any sort of “Evil Google” nor sinister New World Order surveillance. This is merely a logical outcome of social networking, social media and our own cultural preferences for communication.
Nevertheless, whatever you share on the internet is timestamped and saved on servers. An alternate or “alt” identity means nought. It is highly probable that either Google’s Social Graph API depicted above (and well documented for any and all to review) or the Facebook equivalent can put the pieces together.
If you really must say something that you wouldn’t want entering the internet Zeitgeist fire hose, make it password-protected, or adult-content category. Or any similar form of restricted access. In that way, you will effectively be protected by a different level of privacy criteria, or so I’ve heard.
