You are Tinder/Ashley Madison stating you want to tackle Facebook and become a social network overnight by making all profiles made in private public.
And your tone deaf response is to keep repeating "WE ARE NOT PUTTING DETAILS JUST YOUR NAME".
Well, what should people that have been married for 15 years do?
While this is so disappointing is that you could have easily executed this by making it opt it. Possibly with a new name.
Email everyone and say we are starting byte.com - LinkedIn for Engineers. A load of people would have signed up and you take it from there.
But you wanted to take the lazy way out and think about today only.
Be smart and retreat.
