> Facebook in particular has allowed me to keep in touch with a much larger social circle

For me, Facebook offered a false sense of being social. The more I used it, the more I craved social interaction, leading me to use it even more. It's possible, maybe even likely, that I was "using it wrong." But after I used Facebook's tool for dealing with this problem (the Delete Account tool), I've become a more genuinely social person.

I do miss out on photos posted by my extended family. That is a genuine loss. I've probably also missed out on some events organized through Facebook. But then again, I'm making more of an effort to actively maintain relationships offline, and it's probably been a net positive.

Of course, that's just my experience. There are 1.5B active users who might disagree.
