For a preview of what we're dealing with if you happen to be unfamiliar with the type of company these folks are running:
"Can I send an invite via e-mail address?
Unfortunately, we don't have an e-mail invite option yet. You'll need to have the mobile phone number of the person you want to invite saved in your phone contact book. "

Based on that? The answer is, "No, I have no interest in a social media app that requires you to let it invade the privacy of your phone contact list to work."
