This isn’t the monthly Facebook-has-jumped-the-shark warning that people post in seeming anticipation. But with all the discussion of privacy concerns in light of Facebook’s last round of “upgrades,” I am wondering if it’s all gone too far. And I’m not talking about invasions of privacy.

Ever since people were given the opportunity to “like” things from the web at large, my news feed, and I’m sure yours, runneth over. I’ve hidden more friends (but not YOU!), I’m reluctant to accept offers to “like,” and I find myself spending less time on Facebook in general. The endless streams of who likes what are forcing me to acknowledge just how much of a time-waster Facebook is.

Before, I could focus on the social aspects, such as reconnecting with people I lost track of that I actually do like, and making new “friends” that I’ve never met or only know peripherally but enjoy trading witty or profound comments with. By hiding Farmville and its players, ignoring quizzes, and otherwise trimming the fat, I could feel that a lot of the time spent on Facebook was worth it, both personally and professionally. But Facebook is trying my patience.

I recently read that more people access Facebook than online porn, so that’s saying something. But if we continue to be asked to care what every single friend likes, who they’ve become friends with, AND how they scored on that quiz, I’m willing to predict that it won’t be long before we all begin to take a hard look at what we’re getting out of Facebook and how much time we’re putting in.

Even more potentially annoying is the Facebook version of Foursquare, wherein we can know the whereabouts of every friend at every minute of the day. Again, it’s not just the privacy concerns, which almost block out the sun, it’s also the question of how much time I can take from my life to observe yours.

I don’t think the idea of a Facebook will die. But as it continues to pursue profitability by thinking of new ways to deliver consumers to marketers, it will be viewed differently. I think new networks will come along that will offer less — and to me, that will be more.
