I've decided that I've finally had enough of social networking. The privacy issues have been written about countless times by people far more eloquent and informed than me, so I won't go into them. Beyond those, the biggest problem remaining was that social networking is a huge time sink for me. Granted, a lack of friends using Diaspora and Identi.ca guaranteed that I never spent much time on either service. Since quitting Facebook back in October, though, my time spent on Twitter skyrocketed. Looking at it, though, I realize I wasn't actually getting much out of it other than a means to kill time. Furthermore, analyzing my own posts, I realized I wasn't contributing anything either. If there's anything worth saying, it will be worth saying long-form here on this blog.
As for anyone who depended on social networking to keep up with my life and stay in contact with me, I recommend subscribing to this site's RSS feed for news in my life and using good, old email to reach me.
If a more sane, restrained form of social networking emerges, which allows me to be better in contact with my closest friends, then I may consider using it, but until then, the firehose form of social networking offered by current services just won't cut it.
