Information has value.<p>Posting everything under my username doesn't create sufficient value for me. <i>Managing</i> my real-name profile is of some interest, and I do this to an extent, though largely it involves keeping my real name (or well-established) userIDs limited, while conducting most of my online interactions under various pseudonyms. These give me freedom of movement and expression and some freedom from tracking (though I'm under no illusions a dedicated national actor would have trouble finding me should it choose to do so, nor, quite likely, others).<p>What I've observed having been online for several decades is that most people seem to go through a lifecycle of online activity: early exploration, a wide-open persona, and often, starting once "life gets real" (usually somewhere in their 30s or 40s), either a withdrawal or a far-more-managed persona. I can point to numerous "public figures" of the 1990s whose online profiles are vastly more constrained: Jenny of Jennycam, Eve "pi girl" Astrid Andersson, Philip Greenspun (actually fairly active), Xeni Jardin, and many others. Even those who are still active are much more ... controlled in their presence.<p>If you're in your 40s or older and have a significant online presence, odds good are you're in marketing.<p>Even the principles in social networking have ... limited exposure. Sergey Brin's most recent public G+ post was February 20, 2013. Larry Page posts something banal and/or product-related once or twice a month. Page's wife and girlfriend (may they never meet) have been conspicuously absent of G+ since news of status changes (not posted to G+) broke in August. Curious in the case of the girlfriend who's in Google marketing ... but has been posting of late to Twitter.<p>Yeah, life has a way of getting real.
