This may get downvoted, but I hope not, as it's a genuine question:

Why not just use AngelList? They do a lot of curation, you can have custom groups (I'm sure Naval would set it up), and there are already reviews and qualification of investors, big and small. Rather than having a totally separate list, why not leverage AngelList's network and also benefit from the increased awareness/signaling of being able to state someone is invested and share among their network?
