I deactivated my Facebook account again because it was proving too interesting and time-consuming! (Can't you all start leading less interesting lives?) I'm also troubled by various privacy issues, but that's really secondary.
"Deactivated" is really a misnomer; all one needs to do is log back in again. So, if this FB-vacuum is too much for me to take, I'll just return. But in the meantime, you all know where you can find me.
