That's a great point. Definitely a human factors improvement that should be implemented.

That's a really interesting perspective. I thought of the anonymity piece as a feature more so than a limitation. For example, you want to share something between two people, but want to "burn after reading". This way no one can associate the message to the two users or get access to the contents. The requester can always clear their local storage of the key. For example, it would be really useful when sharing information between a whistleblower and a journalist. Identity comes from the medium you share really in this case.

Also an interesting perspective. I didn't think of the lack of built in identity authentication as a feature.

I guess my only point is that it should be clear that's how it works so people can take appropriate precautions in either case.
