you have no idea what you’re talking about.
Actually I do. I have run several forums and been an admin for earlier social media systems.
Trust me - if you have a launch with tons of fanfare then can’t get reasonable numbers of people in to a working system, the people you can’t get in will leave and they are unlikely to be back.
They would have been far better to set low-key expectations of “We are soft-launching this and it should be considered a public beta test so we can iron out problems.” Instead it was presented as fully functional when it clearly isn’t. The internet is not terribly forgiving of that.
