Having a lack of friends on FB does not equate to having a lack of friends irl. I, personally, hate social media. I have like 4 friends on my FB page, and none of them are related to me. We're connected for business purposes, and nothing else. Meanwhile, irl, I have tons of friends and a very active social life.
That's kind of a silly requirement. Seriously. And it also shows me your mindset, if you believe that everyone on this forum connects with people they know irl through FB. I keep my work and social life completely separate for very obvious reasons. But it's not my idea or my group so do what you feel.
