Ok, as "a member of the tech elite", I still have no interest in joining this after reading the features and description, and have little understanding of what it is exactly (sure it's "decentralized" and "private", but even if I cared / believed it could deliver on these promises, these points have little meaning UX wise -- what the heck is it going to look like / use like on my phone?).
I'm mainly making the point that their landing page has done a pretty bad job of explaining and selling the product.
