I wonder if, in the future, being able not to be on any social media will be an higher class privilege.
I think it already is. I recently deleted my FB and Twitter accounts. I had to keep my LinkedIn account because a recruiter told me that if I didn't have at least some online persona then I was weird and wouldn't be hired. I guess I'm not rich enough to delete all my social media.
That usually gets the recruiters out of my hair.
