I have no idea if it's "worth it." What you see is the sweat of Stu's brow, not mine. All I can say is this: If you celebrate the idea of founding things, then you celebrate the idea of building entirely new things and finding out if it's worth it, and dealing with people who complain that the old thing is good enough.

Also, I could be wrong about this, but I don't see people moving to it any more than people moved from HN to Facebook or vice versa. Different communities for different purposes.
