Huh, I'm from the few who never even created a Facebook account. Whenever something is up, everyone knows I won't get the memo, and they give me a mail/text/call. Usually more than one person. And you can't compare that to email vs phone. Phone is costly, time consuming, single threaded. Sending a message on Facebook or an email doesn't make any difference.
