Well, I've taken the plunge: I'm on Facebook. While my publisher has been encouraging me to do this for a while, what pushed me over the edge was closer to home: our oldest son has gone to college, and the low-grade mourning I've suffered in his absence was just enough to cloud my faculties and enable me to sign-up as an attempt to stay in touch with him.
I'm hoping the kids will give me some tutorials over the weekend, because right now I'm pretty much completely lost--roaming around clicking, sharing, liking, friending without direction or discretion. I suspect I'll always feel more comfortable in the more static, sequestered environs of the blogosphere.
