I didn't say anything about being completely cut off from all your contacts. I said, how will people remember to invite you to events, other than by your 5 closest friends who would jump through the hoops of - sending you an email? Or text message.

I don't mean as some theoretical exercise, I mean practically speaking. In fact, a lot of totally public events are only listed on Facebook anyway. The easiest thing to do is to invite people via FB. The bar is raised dramatically by making people send an unsolicited text message or email, if they even have your email address.

I just coordinated a meetup via email. Unbelievably awkward and high-friction.
