I'm curious because I'd bet you're right that such a thing would be adopted really quickly if it were user-friendly but my biggest question is whether everybody would be limited to a single identity or if you'd allow multiples. If you allow multiples, would 'identities' be free? If so, I'd be concerned that the same thing would happen to your company and product that happened to Web 1.0: In THEORY we'll all have control over our own data, but in actuality, running software takes time, expertise, and money, so aren't we all (meaning the general public/average person) going to have a choose an intermediary anyway? And you think it should be your company. (Which maybe it should, idk). I'd also be a bit concerned about: - Ability to spin up alts and anonymous pseuds is a key component to Internet use, for me. One great thing about email is how easy it is to get an email address; I don't need a credit card, address, ID, etc. I don't need to use a real name. And so on. This is one of the things that makes the Web so powerful a force for the marginalized. For instance, I had an email address when I was 6. That's illegal now, but 13 year olds can have them. Or say you're a lady in Afghanistan. - This information persisting over time and being unalterable might result in some very uncomfortable social situations if people keep the same credentials for decades. None of this is a reason not to do such a thing, and I think it's a good idea and one I'd actually use in a heartbeat, I'm just not under any illusions I'd be doing much other than switching my 'alliance' away from an email service provider.
