I've long thought about a social network where each user is required to verify their identity. That comes with its own problems of course, especially in the current times of data protection, misuse of data and a lack of trust for these kinds of things. I'm sure it can be done properly, but who's to say what "properly" means.
I'm working on bringing e-IDs to more people which would make ideas like your much easier to implement. If you want to make your idea reality I'd love to collaborate!
One day, maybe... I am focused on my business at the moment (check my profile here on HN).
A social network is certainly not a small undertaking but I can see it starting off as a side project and building a small community. I can forsee lots of costs involved however. I will keep your offer in mind!
